Haha MXE and gaming is so much fun. When I play battlefield I almost feel the bits of dirt and stuff flying around me when a shell hits nearby. If I filmed myself playing I'm sure I'd be ducking and dodging to the point of almost falling off my chair.
I also find it very difficult to not start humming flight of the valkyries on skype when I'm in a chopper with some friends on the way to the frontlines. Sound is very important on MXE and Battlefield 3 has some the crispest sound ever. Too much MXE and I'm utterly useless though, just standing around looking at my guns or tacticly sneaking around in my own base when we have capped most flags.
Assassins Creed 3 was also alot of fun on mxe, especially the naval-battles were intense as hell.
Path Of Exile... ehh well. The game is pretty advanced, with some important decisions that can totally ruin your game character later on and has strict penalties for dying. It works on the lower levels, but later parts of the game leaves me feeling retarded if I'm any kind of fucked up while attempting to play.
