Ultimate gaming battle

What is your favorite system and why as well is favorite game for that console and why.

Mine is the Xbox360 for the fact of online play that has gamers who like to game; My favorite game is Call of Duty: Modern Warefare 1 for story and multiplay online

PS3, because:

DS - meant for kids around 12
360 - Too many 10 year olds who love kicking IP's
PS3 - Blu-ray, free online, Netflix, and just a PlayStation fanboy.
Wii - meant for little kids
PSP - Getting outdated imo

Nintendo DS - One of my favorite consoles. So many good RPGs.
Xbox360 - The console that I play every day. It's cool to play online with friends.
PS3/PS2/PS1 - PS2 has so much good games, I played it for years.
Nintendo Wii - Good console and sometimes an awesome game for it is released.
Sony PSP - Never liked it.

My choice is Xbox360 or the Nintendo DS.

I reckon the Playstations except for the PSP. Ive grown up with PS1, PS2 and now PS3. Just love the variety of games, but it seems xbox has some good points as well. Such as Halo especially.
Nintendo DS has some decent games, but mostly i don't seem to fancy it. But i dig the new DSi.

Xbox 360 because it's just amazing.
