^^^^^PS3's are having problems. You really are not supposed by the system at launch. You usually should wait a couple months or so. No system has never been perfect right out the gate.
360 is more established with titles then PS3.
Growing up I played all systems. I think that being a fanboy for one system is very lame. Every system that has come out has had great games for it. For Example
X-Box- Halo, Chronicles of Riddick, Jade Empire, Star Wars: Kotor All Good
Nintendo- Castlevania 1-3, Ninja Gaidan 1-3
DS- Castlevania PoR & DoS,
Wii- Metroid Prime 3, RedSteel, an Zelda
X-Box-360- Halo 3, Lost Planet, PGR 3, Half Life 2 Orange Box
PS3- Half 2 Orange Box, Oblivion
Gameboy-(Orginal)- FF, Castlevania, Tetris, Mario
Gameboy Advance (an SP)- Castlevania (all of em), Zelda, Lego Star Wars
PSP-Castlevania
Gamecube-RE 4, Metroid Prime Series
Nintendo 64-WWF VS games, Castlevania, Zelda
Super Nintendo- Castlvania, Super Mario World, Final Fantasy
Playstation 1- Suikoden 1,2, Castlevania, FF7, Breath of Fire III
Playstation 2-Suikoden 3-5, Tactics, Castlevania, FF10
Neo Geo-King of Fighters, Metal Slug
Sega Genesis- Shining Force, Phantasy Star, Sonic
Dreamcast- Tokyo Xtreme Racer 1&2
Game Gear- Shining Force, Sonic
Neo Geo Portable-Metal Slug
PC- Galactic Civilization II, Alpha Centuri, Half Life, Fear
Philips Cdi- N/A
Atari 2600- Boxing, Moon Patrol
Atari 5200- Moon Patrol, Vanguard, Kangaroo, Beserk, Robotron
Atari 7800-Q-Bert and the Ship Racing game (???)
3D0-N/A
Turbo Grafix 16- Splatter house
Master System- Phantasy Star 1
I have played all of these games and owned almost all these systems or played emulators of them. This goes to show that there is no clear cut best system with the best game. Metal Gear Solid 4- Coming for the 360. Devil May Cry 4-360. Only Sony and Microsoft and Nintendo Made games will be left.
