I really, really need a good new game to play. Tell me about your favorite game. (GAs inside)

snakebird. you get to move around these snakebird looking cuties... and it's deviously deceptive.

FTL: Faster Than Light?! I can't see it on your games list, I doubt I have to give much intro to it, it's brilliant. Go get a copy and play it, if you have a copy then install and play it.

Darkest Dungeon You have a strange mix of games on your profile with high play time, so I don't really know what genre to shoot for. This is a great game, well worth a look. It's bloody hard though, not for the feint of hearts but with a high time in some difficult strategy based games I reckon you could like this.

Anno 2070 High playtime with Civ 5 lends itself to you liking turn based strategy type games, I enjoyed the brief amount I've played of this.

The Immortal.

Freedom Planet, If my top timed game in my most played games doesn't just tell you I enjoyed it I can honestly say it has LOADS of replay value if you want to go faster and better then your previous run.

I am not sure if you grew up in the 90's but its pretty much the swansong of all things Sega Genesis titles. Such as Rocket Knight, Gunstar Heroes and Sonic the Hedgehog. Not just that but also Megaman X and Mario as well in some instances.

A must have for Platforming games on PC. You won't regret it.

If your looking more into exploration and puzzles not of Speed Platforming then I also suggest Nigoro's La-MULANA http://store.steampowered.com/app/230700/
Explore into the hidden depths of La-Mulana where Puzzles and deadly traps await you to challenge for riches and mysteries.
Homage based towards to Castlevania games. Another pick of mine.

I don't think you'd like to play my favorite games since they are all strategy.
