It's...hard to say what qualifies for me. The weirder a gimmick of a game is, the more I like to play it. If tomorrow someone releases a game where you play a blob of peanut butter in search of the end of the rainbow where the main mechanic is a cross between a rhythmic game and a real time strategy game, I'd wishlist it...sort of speak.
Anyhow...I skimmed over my steam review lists. At least these, I wouldn't have expected a thumbs up (or at least not as strongly as I meant it)
Offspring fling: you play as a fluffy mascot and you throw your own children?
Hexus: a mix of city building and match 3 gem matching
Freecell quest free the land of evil by playing...freecell card games!!!!!
Learn Japanese to survive: this is just stupid: a very simple turn based RPG in early FF style (which really ISN'T my cup of tea), but hey...it has you learning hiragana. That's two negatives, so when you multiply these...you get something positive.
The static speaks my name. Okay, this one isn't ironic, but really...the game is ten minutes long. Ten minutes. Even so, I think I can still recall every second of it.
renowned explorers. Okay, more a matter of guilty pleasure, but hey...an RPG where you use verbal que's (threaten, excite, bully...) instead of actual attacks.
ad-venture capitalist If I'll ever end up in an GA-meeting (Gamers Anonymous), it'll be because of this game. It is so terribly bad and stupid that I literally have to pull myself away. I even downvoted it because I don't want others to start it (note: I haven't really
played that many hours...the game even rewards you for NOT playing

).
...and finally: two games that are balls out awesome, but deserves mention here because of the huge risk they took (meaning: if they weren't so cool, then they would have faceplanted...HARD)
Jazzpunk: have you ever seen one of the 'naked gun' or 'hot shots' movies? Yes? Well...this is these movies, but in video game form.
roundabout: the premise of this game is so stupid it's plain out genius: "you drive a limousine that constantly spins around". That tells you all there is to know about the game, except one thing: it has the best cutscenes in the history of video games!
