Not sure what i have that's worth playing still

You have too many games, Steam crashes my browser.

Metro 2033? I see you have less than 2 hours on that one.

Portal, divinity 2, and...wow you have a lot of games really

Your Profile via SteamDB... -- scroll down to the table that lists all the games you own, and click on the Reviews table header to sort them by review percentage, descending. Compare to playtime, and go at it! :)

Wow 900h on Dont starve together...thats impressive xD
Guess I dont have to recommend it ^^

You should play Duke Nukem: Manhattan Project, and Overlord II.
Both are a breath of fresh air...the former an old-school 3D platformer (with some of the best music I've heard in games), while the latter has "unit command" gameplay; you are a demon overlord that commands your minions (mini-demons) into battle and destroy enemy bases.

1. Zafehouse: Diaries - Interesting take on surviving a tough situation as a team. You might not love it, but you should at least give it a look, because it's unique!
2. Unity of Command - Very good, and really approachable operational level strategy game. Easy to learn, hard to master, and one of the best games I've played on that "level".
3. Thief Gold - It's Thief. Still the best stealth game on the market. The new Thief is pants, don't play that (unless you like reloading because you got stuck in something for the 8th time!)
4. Realms of the Haunting - Good horror-themed shooter (not really horror, just horror themed) with fun FMVs and great environments.
5. Papo & Yo - Lovely and well told story that touches on some really dark subjects. A must play.
6. King of Dragon Pass - It's unique, like nothing you've ever played and probably like nothing you'll ever play. Strategy, RPG, adventure, chose your own adventure and with a dash of management, plus a really interesting setting. Also, ducks.

I'd definitely recommend Super Meat Boy, Darksiders, VVVVVV, Trine 2, Hard Reset, Sonic Generations, Brothers, and Half-Life 2 (and of course episodes 1 and 2 (I think you own those)).

10 games from your list I like and you could try them(mine and my friend experiences)

Brothers A Tale of Two Sons! It is an amazing game, played with my friend at his account.
Mirror's Edge
Dragon Age Origins
Switchcars
Binary Domain
Megabyte Punch
Lara Croft and the Guardian of Light
Rochard
OlliOlli
CrossCode

You've got four FF games. Go play those

Banished was so much fun, and it has a steep learning curve for a lot of people.

Brother - A Tale of Two Sons, amazing game!

Puzzle Agent games are short, but a lot of fun. Charming, I'd say.

If you haven't actually played Skyrim, that will suck away part of your life.

http://store.steampowered.com/app/312970/ this is good for you Villan

You have several games I've really enjoyed that you haven't even touched:
Braid
Brothers - A Tale of Two Sons
Galcon Fusion

Also there are a few more that you've played for a few hours, but which are definitely worth going back and finishing (they're both short):
Limbo
Transistor
