Okay, I don't mean to get all "fanboy-y" but Metal Gear Solid 4 is not just a "good" game. I really am not trying to inflate the value of it, but it is an epic--strangely anti-violence--story about the events that shape us and what we fight for, and it covers everything from bioethics to patriotism. On top of that, its gameplay is extremely open-ended and challenging. I say this mostly because . . . I am obsessed with MGS games. That fact aside, I don't believe I love this game because I love Sony. I'd be the first to petition to get the game on 360(and hell, if they could do it, on Wii).
I own a PS3 because so far only five games have wowed me on the next gen, BioShock, Little Big Planet, Metal Gear Solid, Mass Effect, and Oblivion. With a computer and a Ps3, I can cover all of those. This is the hitch, though. "Any good game will be multi-platform" isn't entirely true, but often correct. It is more likely for a 360 game to also be on PC (windows and all that) than for a PS3 game to be on PC. So, for me (and I stress "for me," because I seem to come off caustic in all forum debates >_<), who's too clumsy to play action shooters and too "immersive" to play many games, a PS3 and my gaming PC suit me fine.
I hope there are no more screaming Sony apologetics out there. I sure haven't heard from them in a while if there are. What seems to be happening now is a new breed of "anti-Sony-apologetics", 360 fans who specifically knock Sony's work.
But hey, where would the world be without conflict? Play an MGS and wonder.
