IL2, Even tho i´m totally crap at it. Its still fun. Back in the days i also played WW2 online, and was mostly flying stuka bombers. Tons of fun.
Flashpoint and ARMA series are the game that covers infantry/armored combat. (Only BIstudios, not the new dragon rising franchise ripoff)
I also enjoy racing sims like GTR / Richard burns rally..
I have a hard time playing arcade style games for some reason. The more "realistic" the game, the better. I guess its because i like games with steep learning curve, It gives alot of satisfaction once you learned to master them =)
I do enjoy to play MW2 online for some reason. Doesn't get more arcade
