I've got a butt-load of games in my backlog.. I'm asking YOU PEOPLE which I should start with...

Double Space to break.
Why don't you give me some of your games, i will try and tell you which one is good.

Line Breaks: I usually just click enter or use ----------- if that's the case...

I'd be interested to see

Cave Story +

Space Pirates and Zombies

Orcs Must Die!

Trine

Legend of Grimrock

Order doesn't matter though :X, thanks for the giveaways too!

Bastion, Deus Ex, E.Y.E, Half Life, Orcs Must Die!

Doesn't has to be in that order.

For line breaks press enter TWICE.

Play Mass Effect 1 and 2, also, play Femshep. Dare! Double dare!
If you want a custom one but blow at the CC, check out this site for shared facecodes.
Great games, you'll like.

Man, my backlog is bigger :|

But out of those, Trine and Bastion first

Fallout 1 and Cave Story

start with amnesia, you'll get the guts to play other games...

wait, you dont play Half-Life yet?... what the fuck are you doing here then!?... GO PLAY THAT GAME NOW...
also Magicka and Really Big Sky are pure Fun, RBS is that thing that you need win just have a couple of minutes to play

P.D: PLAY BORDERLANDS OR DIE

The Batman games

Psychonauts, Bastion, Aquaria, Half-life series, Amnesia and Legend of Grimrock.

Half-Life series IMO :)

Whenever I approach a backlog of games (I'll admit I never had a backlog this large though) I start with games that have low replayability, otherwise I might get stuck on one game (for example I could just keep playing Rome:Total War or SPAZ on and on with new campaigns, and never get to the rest of the backlog). These tend to be story-driven or puzzle games (since once you hear the story or solve the puzzle there is no need to redo them). Then among these low-replayability games I usually start with the shorter ones to keep me motivated to finish.

Using my two parameters listed above I would recommend you start with Bastion, Trine, and maybe Amnesia and then work your way towards KOTOR, Deus Ex, and Psychonauts.

Psychonauts, Bastion then either Batman Arkham Asylum/City or Mass Effect 1 & 2

Rome total war, it's a great game! :3

Bastion

Psychonauts, Knights of the Old Republic, Trine/Bastion would be my top 3(/4).
KotOR was better on the Xbox, if for no other reason than a better control scheme, and speaking of the XBox, but not related to your list... Jade Empire was awesome.

OMG I realllly need Titan Quest's expansion.
I have the first one and I loved the game and even went to download all the mods on the game to extend playing time. I would love to have the expansion. What can I do to get that game ;P.

Deus Ex series. Play 1 and 3, and you can pretend there was just a big gap between the games.

Bastion is good, but it's not the orgasmic game everyone is touting it as. Cave Story +, the Batman series, Half Life, KotOR, and the Mass Effect series are also good choices to start off with. You should probably break up your AAA titles with some of the indie bundle games, so you don't exhaust your list of longer titles immediately.

loled

You haven't played Legend of Grimrock?!?!? Why do I not have the money that you do :(

Alan Wake has a really engrossing story, and Batman AA, and AC are really fun to play

Amnesia: The Dark Descent

time to die being scared

Amnesia, please good Sir. :(

play Puzzle Agent 1 & 2. you will not regret it. plus you can get through them quick!
