He likes the NHL hockey type of games, and games that you play head to head on.
That's tough, a good NHL on a modern console system....
Frankly, NHL06 is the a great game. Otherwise you have to go back to something like 93 to get something decent.
The best way to generalize the consoles:
PS2 and xbox are great with sports games. However I give a little edge to ps3 because the controller layout is better for sports. The plud for xbox with sport games is many upgraded the graphics. The xbox controller isn't bad but I find the dual shoulder button layout is better for sports.
The cube is decent for sports but not graphically the same. But it has the nintendo titles like super smash bros, mario party, etc that make great party games.
PS2 also has addicting titles like Katamari and guitar hero. Xbox has better networking capabilities.
So, if he is more into the sport games and does't care about networking with other people go PS2.
Otherwise, if he could pick up a dreamcast I still think that is the 2nd best console ever made (1st being the NES). I still play bomberman, nfl2k, nba2k, worms, gun games, soul caliber, rayman 2, MDK 2, Revolt, etc...
