The 360 has a heap of good games that aren't sport and racing...it's got nothing to do with being 'hard' and 'cool' the games are just fun. It's got the widest range of genres compared to the other consoles. ie: brilliant rpgs, shooters, sports, puzzle, retro and it has its fair share of strange games on xbox arcade too.
weird, fun and interesting Japanese games have their place and I think they're excellent, the DS has some really good games of that type. the Wii has a shithouse lineup of games although mario, smash bros and metroid make owning one worth it.
You can't go by numbers of consoles sold to determine which one is better, most people are stupid and just buy whatever is the most popular. In the Wii's case heaps of casual gamers are snatching them up because of the dumbed down and gimmicky controls. A few games on the Wii will be good but the vast majority suck so bad. The few nintendo gems make it worth owning as I said before.
here's a list of some fun games on the 360, these are all very good games:
Gears of War
Bioshock
Elder Scrolls IV: Oblivion
Tom Clancy's Rainbow Six: Vegas
Dead Rising
Crackdown
Forza Motorsport 2
Geometry Wars: Retro Evolved
Lost Planet: Extreme Condition
Dead or Alive 4
Burnout Revenge
Tom Clancy's Ghost Recon Advanced Warfighter 2
Eternal Sonata
Viva Pinata
Call of Duty 4
Halo 3
Half-life 2, episode 1, episode 2
Blue Dragon
Portal
Team Fortress 2
Stranglehold
Mass Effect
Halo Wars
Rock Band
Guitar Hero 3
Assassin's Creed
Skate
Resident Evil 5
Ninja Gaiden 2
Devil May Cry 4
Soulcalibur IV
Beautiful Katamari
Left 4 Dead
(not all of them are out yet, most will be by the years end)
So as you can see the 360 has a wide selection of games that are not just sport and racing games. If you're a so called 'hardcore' gamer the 360 is the best console to own by far.
The psp will never overtake the DS because the japanese will keep buying them for the casual games. Now that there's a final fantasy game on PSP the Japanese will start buying them by the truckload, it won't sell more than the DS overall though.
The PS3 currently has not much going for it but over the next year several must have titles will start to appear and the price will drop. The japs will start buying it once the new final fantasy is released..no doubt.
This generation of consoles is awesome and I'm looking forward to owning most of them eventually.
Yes, quite a long rant...
