Recommendation engine: Downvote any game you've heard of before
This might be a slightly unusual attempt at a prompt, but might draw some appealing unusual options.
The way it goes: Suggest games, ideally the kind that you believe would have relatively broad appeal. Don't feel bad about downvotes, but do downvote any game that's suggested if you have heard of it before (Perhaps, give some special treatment if it was literally your game of the year). This rule is meant to encourage people to post the indie darlings that took some unusual attention and discovery to be aware of and appreciate.
If possible, link to the Steam pages for the games in question, so that anyone interested can quickly take a look at screenshots and reviews. And, as a general tip, anything with over 1000 steam reviews probably doesn't belong here. While I'd recommend that you only suggest one game per post, at the very most limit it to three.
If I am incorrect about downvotes being inconsequential account-wide, say so and it might be possible to work out a different system.
Tin Can
Tin Can is a space survival simulator, where you are trapped in an escape pod after the loss of your ship. There are a few systems in your escape pod, and each system has components you need to look after. Your pod regularly flies through astoroid fields & other space phenomena that break these component parts forcing you to repair, replace or do without the systems keeping you afloat.
Downvoting per the rules, as I spent months obsessed with this game, having notes with the codes open on my second screen. Excellent game.
I did mention in the rules, if it was good enough to actually be your game of the year, you can make an exception. (I’m trusting that doesn’t mean we see Baldur’s Gate 3 on top or something)
I don't think it was my GotY, but still an excellent game
Requisite downvote, but also mention that the devs of Tin Can are about to start alpha testing of their multiplayer sequel named Space Chaos.
