I tend to be partial to indie porn games that emphasize gameplay, so potential players of Just One More Chance who want every game to be a ren'py visual novel should take my review with a grain of salt.
Just One More Chance is one of the most ambitiously new takes on life sim porn games that I've seen in quite some time. It combines the following genres: Groundhog Day, immersive life sim, roguelike, stat builder, dating sim; and does so in a way that I actually find very fun. The backstory is pretty simple: the main character is a severely overweight loser whose life has gone downhill, who got selected by a shady sci-fi company to relive a simulation of his first couple weeks of college with the ability to make different choices in that simulation. The result is a roguelike stat-building dating sim, where each time you finish a loop you take some prestige currency (experience), achievement bonuses, and a portion of your stats from the previous loop, and run through it again trying to see more stuff and 'get further' in various ways.
While this style gameplay had the potential to get boring quickly, seeing the same things over and over again; the dev has worked hard to make the sex scenes well-written, diverse, and give the player a lot of romantic options to explore. Since achievements give gameplay bonuses, there's also an in-game incentive to see the range of sex scenes rather than just grinding out experience through just having lots of sex and making money (which you can also do, if you prefer). One especially smart move on the developer's part is the virginity system, which is basically just granting a unique achievement when the main character loses his virginity in a particular loop to a girl he hasn't lost his virginity to in previous loops. You can only get one virginity achievement per loop, and while there are some 'easy' girls, it's often a challenge to find a way to make sure you only have sex with a particular harder girl first, resulting in some more variation on gameplay strategies depending on who you want the main character to bone first than if your goal was just to have as much sex and make as much money as possible per loop. There are lots of different girls to screw, with different body types and fetishes and preferences, so there's a lot of variety to what sex you'll see in the game.
That being said, the game isn't perfect. While grinding is very slow and ineffective in the beginning, once you get your money-making rolling via freelancing it becomes very easy to get massive amounts of experience per run. This is somewhat offset by achievements granting unique bonuses, but it still trivializes the major prestige currency of the game once you figure out how to maximize your coding and intelligence at the start. Diminishing returns might be a smart change here. The UI is rather simple, the stats are a little opaque (stress, for example, seems to do a bunch of things but not always consistently), and with a few exceptions I tend to find the girls' relationships with the main character more or less play out the same way once he builds up his stats. It also wasn't my favorite thing when Natasha's backstory was changed, but Patreon be Patreon after all. Being able to change up some relationships or have characters more related to the main character's backstory might be nice. It also might be interesting if the 'outside the Animus' scenes between runs had some things to unlock too.
Still, Just Once More Chance is fun, it's sexy, the dev is clearly putting a lot of effort into improving this game with frequent and regular updates, and I highly recommend anyone who finds this type of game potentially interesting to give it a look. I'd give it 4.5 stars if I could, but I think given its uniqueness, it makes sense to round the score up to five rather than down to four.
