SSX was the best "All around" type game for me. Everyone I invite over enjoys it the most
Timesplitters is fun but is frustratingly difficult at times, and get redundant in story mode.
DOA2:HC looks great but I am not much of a fighter fan, I find myself button mashing and winning, but I picked up a strat guide and will study some moves to become more proficient
Armored Core 2 is excellent. Its tough and very frustrating early on especially if you are not familiar with the AC series. The game seems almost designed for experienced players. Still I picked up a strat guide which help me to understand more about the parts, I get my ass kicked regularly but some of the missions are fun. The game looks pretty damn good too IMO, not blow me away but nice
The Summoner was fun but had its bugs, if your a diehard RPG nut you\'ll get enjoyment out of it for sure
