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.
Magnetic By Nature is a 2D platformer where you are generally using either attract or repel mechanics. I came across this game on the PAX East show floor, and it really wowed me. I may be one of only a few hundred people who ever played it. There’s a bonus chapter, after the credits, that was kind of bullshit, but the 7 or so hours of gameplay before it was fun, challenging, and unique. Initially available for like $15, it’s now down to $1, and it’s a steal at that price.
