Ok, THIS is the game they need to finish. I am really happy with what we have here, that I'm not going to buy any other games from them until this is finished! I know I'm not the only one as many are saying it in discord too. One you get this unreal version, you can never go back. Finish this!
Unreal Lust Theory is a really exciting step forward for the series. Seeing Lust Theory move from 2D to full 3D is a huge upgrade, and I really appreciate the direction the developers are taking. The character models look great, the animations feel much more dynamic, and being able to interact with the girls in different positions adds a lot more depth to the experience. I’m genuinely looking forward to seeing how the final release turns out. Since this is still Early Access, the career mode currently only covers the first three days of Season 1, so there’s no adult content in the story yet. That part is a bit disappointing, and I really hope the full game will eventually include the entire series. On the positive side, the sandbox mode already lets you enjoy scenes with the female characters, and there are some fun little easter eggs hidden around the house — including one involving a shotgun near the stairs that leads to a special scene with the blonde character. Overall, I’m excited for the future of this project. The foundation is strong, the 3D direction fits the series perfectly, and I hope the developers continue expanding the story and adding more content. Wishing the team all the best. I’m looking forward to the full release.
等待制作组更新,场景没做完开放世界一堆白模
Worth it, but only if: - You've already played the visual novels it's based on (Lust Theory Season 1-2-3) and are therefore already familiar with all of the characters - You're getting it on sale - You keep your expectations low With those 3 criterias in mind, I like to think of this Early Access game in its current state as more of an experimental DLC, giving more scenes with characters you know and love, in a more interesting way from the limitations you would normally get from a visual novel. Essentially, as of writing this review on July 8, 2026, here's what you can expect; Storymode: Basically the first 2 days of Lust Theory season 1, so no actual scenes as it's barely the setup, albeit in unreal engine so the vibe is very different. Sandbox: in this mode, you simply walk around the house with the 3 women that live there. You can talk to each of them to have sex, which will immediately take you to their respective bedrooms to do all sorts of things with a variety of positions. But you can also have them follow you around the house so you can detect holograms. Clicking on the holograms when you find them means you unlock a new scene. There are also various easter eggs around the house. If you find Ellie's prop shotgun for instance, it unlocks scenes with Ellie. With the latest updates comes an open world outside the house, and if you go to school, you can meet Nicole there as well. There are also special events although per the game's guide you need to actually change the date on your PC to match the events, such as Christmas, Easter and Halloween, which I'm sure add more scenes as well, but it's a bit annoying to set up. THE PROS The scenes are generally great and considering the game's size, they're also densely packed. This might actually be the most adult game I've ever played in terms of scenes to game size ratio. Part of really appreciating the game plunging you straight into the steamy stuff though, is like I said, knowing the original games, as it's those games that give appreciation to the characters, THE CONS - Buggy as hell, mostly in the form of slow loading textures, so characters and objects often appear too late, breaking the immersion. This is mostly while exploring though, not in scenes. - Complete lack of optimization. Especially walking outside, it's extremely laggy despite the visuals not being particularily impressive. - Visuals can be very rough around the edges, in the school for instance the lighting is abysmal, but that's also true of inside the house. Mind you the devs are fairly transparent about this, there's a message when launching the game that says they're basically just giving you whatever latest version they're working on without any polish, so what you get is also what they're currently working on. That being said I can forgive all of these cons and praise the effort that went into it, but a potentially bigger deal breaker, and I hope I'm wrong, but I don't really see this game ever being finished, at least nowhere near the level of quality it would need to reach to actually be considered good and well polished. What I mean by that is that I don't think these devs have any substantial experience working with Unreal Engine, and have likely never worked on a game comparable in scale to what this would have to achieve to truly feel complete. It's not just polishing what would be a somewhat big worldmap to make it look more realistic, it would the addition of NPCs, travelling cars, adding layers of gameplay that wouldn't make sense in a visual novel but would be expected here. They're clearly learning as they go, as they released the Early Access nearly 2 years ago what I'm seeing is good, but very slow progress. If they do finish it that could be years from now. Hence the criterias at the start. If you tick all the boxes the game is pretty good, I enjoyed looking for the holograms and easter eggs, and the scenes are great. But updates are every few months and the changes largely incremental. If they pull it off, it could be the best game in this genre, without a doubt. But they need a lot more time, ressources, and experience.
Me parece un proyecto impresionante. Seguid así, desarrolladores, va a ser el número 1!!!!
hikaye modu gelirse binalar gözükmemezlik olursa lütfen yapımcı bana ulaşsın
加油,很看好这家制作商,玩过两个作品剧情都很棒,CG差了一点,但是这一部肯定CG不会差,更新报告里都写的关于画面优化的事。很期待成品
Great
《Unreal Lust Theory》中文译名《虚幻欲望理论》这是一款开放性第一视角的成人模拟沙盒类游戏。这种类型的游戏在黄油上是较为罕见,也是有一个非常有吸引的黄油,但把这款游戏做好确实要花费不少精力和时间。目前,我们玩到的版本还有各种小BUG和小问题,这导致了游戏的体验会差点意思,相信制作者后面的更新的完善会让这款不一样的黄油成为神作。 首先游戏是以沙盒为主,一开始我选的是剧情模式,但剧情内容非常少简单的交代了男主和室友的基本情况,然后就去上大学,然后就没有任务提示了,我看了一下评论意思是剧情模式还没开始做。所以想要体验剧情内容的小伙伴还要等一等直接去玩沙盒模式好一点。 沙盒模式相比较下更为简单了,可以在开放世界完成一些任务获得一些好感,然后和各位女主产生一些瑟瑟的内容和环节,其中探索女主们的房间是这个模式最有意思的点会有一些意想不到的彩蛋,期待制作组能添加越来越多的小彩蛋。 瑟瑟方面是CG展示,但女主们的姿势并不是很多,主要原因还是游戏大概制作了5分之一的内容。凭良心说这款游戏如果制作者能把整个沙盒内容填满这款游戏绝对是神作当中的神作了,目前看作者的更新速度和修BUG的速度大概还是要几年了,也许是制作者缺资金找不到更多的程序员一起开发这款游戏,所以本次我给的是好评,希望有更多玩家能看到这款游戏。一起推动这款游戏的发展和更新。
