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.
It's made by the Developer who made Gunpoint and Heat Signature (also amazing games if you somehow haven't heard of them BTW).
It's a turn based tactics/puzzle game where you command a squad of wizards with different magical abilities to dispatch a room full of enemies. A bit like Into the Breach but hand crafted scenarios, not procedurally generated.
It also has a fun story, character customisation, and ability unlocks. Almost every scenario has a bunch of optional extra goals, so you decide how hard you want to wreck your brain. Highly recommend it!
Edit: It seems people are aware of this one, I really thought it was a bit niche.
Yep, don't care, I'm up voting anyway. This game is well done. I loved Gunpoint, I loved Heat Signature, and I've been really enjoying this one. Writing, gameplay, graphics... I'm a fan, for sure. The whole Defenestration Trilogy is worth it.
