Aquapark Tycoon Review

RollerCoaster Tycoon, But Wet

Aquapark Tycoon is a $22.99 waterpark-building sim from developer Boxelware, the studio behind the space sandbox Avorion, released into Early Access on Steam on July 22, 2026 following more than two years of dev diaries, trailers, and free demos that never opened as a purchasable build, so the July Early Access launch stands as the game's clean original release. The pitch is direct: design water slides, pools, and saunas from scratch, keep a stream of guests fed, relaxed, and entertained, and grow a rundown lot into a thriving waterpark empire. Two months into Early Access the reception sits at a Very Positive 86%, with 87 of 100 English reviews recommending it, and the review pool draws the same comparison again and again, this is the RollerCoaster Tycoon and Parkitect crowd's long-awaited waterpark game, arriving in a genuinely unfinished but already substantial state.

Slide Building Is The Star Attraction

The centerpiece feature, and the one reviewers consistently single out as the game's biggest draw, is freeform water slide construction. "The physics on the slides perfectly balances between being a detailed water slide simulation and letting you launch your guests as projectiles," wrote one reviewer, capturing the appeal of a system that rewards both careful design and outright silliness. Another reviewer who came in skeptical, already owning Planet Coaster 2, described getting pulled in anyway: "I played it for 3 hours with no break. It's so fun, there is so much unique content (Like saunas, seasons, indoors and outdoors pools...)." A more measured review framed the whole game against its genre ancestors: "A beautiful aquapark tycoon game that captures the charm and clever gameplay of the classic RollerCoaster Tycoon games. It strikes a fantastic balance between cozy creativity and rewarding management challenges." For players who've been waiting specifically for a waterpark-themed entry in this genre, one reviewer put it plainly: "I tried that waterpark simulator game but was upset that I couldn't design my own slides. This is exactly what I've been looking for."

Co-Op That Actually Works, Mostly

Multiplayer is another area where Aquapark Tycoon draws unusually strong praise for an Early Access release. "Top tier tycoon game, and FINALLY one that incorporates CO-OP and VERY VERY well. I find myself fiening for co op games like this which I can build with my partner," wrote one reviewer, and another confirmed the mode's stability directly: "We already tested the multiplayer mode and it works flawlessly." That praise isn't universal, though, and the complaints that do surface are specific rather than vague. One reviewer bought the game specifically for co-op and came away frustrated by a pacing issue: "multiplayer is locked to 1x speed. This quickly becomes a waiting sim as you have to wait for money to trickle in to progress. I don't want to play with infinite money, but I would at least like to be able to go to 3x speed." A separate reviewer reported a more serious technical problem: "Co-op suffers from severe desync after just a few minutes of gameplay," alongside guests and staff that "randomly stop moving and just stand idle, doing nothing." Both complaints describe fixable, concrete issues rather than a fundamentally broken feature, but they're a reminder that this is still an actively developing Early Access build rather than a finished co-op experience.

The Building Tools Have Real Friction

Not every review is charmed by the construction system that anchors the game. One detailed critique zeroed in on the indoor-building tools specifically: "for a game about building stuff, the building system is HORRIBLE," citing an "indoor" tool that "places ugly walls with random objects, 3 million windows, doors and useless objects automatical[ly]" with little manual control. Smaller but recurring quality-of-life gaps show up across multiple reviews too: no terrain-smoothing tool after flattening ground, no CTRL+Z undo shortcut, and no way to cap how many guests can crowd into a single pool, which one reviewer noted causes pools to look absurdly overcrowded with swimmers constantly colliding. None of these are dealbreakers on their own, but stacked together they paint a picture of a building toolset that's functional and often satisfying in the moment, per the slide-building praise above, but still missing conveniences players expect from a mature entry in this genre.

Too Easy, Not Enough Content Yet, And The Price Reflects That Gap

The most consistent structural complaint in the pool isn't about bugs, it's about pacing and value for an Early Access price. "The price tag is kinda steep for what it currently is... currently it's 10$~ worth of fun," wrote one reviewer bluntly, while another who's been playing since day one described the difficulty as a real letdown: "SUPER easy. There's no real challenge. You don't have to try too hard to pass the scenarios." A reviewer coming from the genre's older classics was harsher still, comparing it unfavorably to free alternatives: "just play Open RCT2, hell even just play Roller Coaster Tycoon 3... I had a way more fun time and had way more options then this game which is very very VERY easy." At the same time, several reviewers explicitly frame this as a fair trade for an actively developing Early Access title rather than a finished product's shortfall, with one writing "there's already quite a bit of content and I didn't encounter any bugs or performance issues so far," and another calling it "so so more ready than most EA games are." The honest read is that Aquapark Tycoon offers a genuinely fun few hours today with scenarios and challenge depth clearly still in progress, and the $22.99 asking price is only comfortably justified if you're buying into that trajectory rather than judging the current content alone.

Scattered Technical Rough Edges

A minority of reviews describe technical problems severe enough to sour the experience entirely: full-screen rendering going black on windowed/borderless toggling when switching to another application, one player reporting the game loading into an all-black world after purchase despite the demo working fine, and at least one reviewer describing repeated crashes on a capable PC. These reports are far from universal, most reviewers report a stable, polished-feeling Early Access build, but they're specific and technical enough to be worth flagging rather than writing off as user error, especially for anyone planning to run the game in a non-standard display configuration.

Verdict

Aquapark Tycoon delivers on its core promise: a genuinely satisfying, RollerCoaster-Tycoon-flavored waterpark builder with a slide-construction system that reviewers keep singling out as the best part of the package, backed by co-op multiplayer that mostly works and, for many players, works impressively well for an Early Access title. The honest caveats are just as clear and just as corroborated: scenario difficulty is currently too easy to offer much of a management challenge, the building tools have real friction around indoor construction and basic conveniences like undo, and a $22.99 price tag is a genuinely steep ask against content that several reviewers describe as still catching up to it. This is worth buying now for fans of the genre who want to support and shape an already-promising Early Access build, especially anyone building with a co-op partner; players who want a fully-realized, challenging tycoon experience out of the box should wait for a few more content and difficulty updates before diving in.
