Your favourite steam game of 2010

[stee01]

So what is your favourite steam game of 2010?

You dont have to own it on steam, it just has to be available on the steam platform.

Mine would probably be Mass Effect 2. Alpha protocol would probably be my next favourite.

Mine varies. I usually don't have just one favorite game, but if I were to choose one, I'd say Call of Duty: Black Ops. Next would probably be Battlefield: Bad Company 2, though I haven't played it in a while.

Left 4 Dead 2 is fun too if you have enough people to play with.
