I have a PS3, among other things. I actually collect games consoles so at the moment I must have 30+ consoles respectively. That would include a NES, SNES and so on; Atari 2600, 5200 and XEGS and you know the rest.
Back to the PS3 I have 20 games exactly, I get all the big releases like Metal Gear and WarHawk but also smaller ones like SEGA Rally. Call Of Duty 4 was definitely a high point, I have continued the series and I'm currently playing Call Of Duty: World at War. I am not like what I would say is a stereotypical gamer but video games do play a large part of my life (as does golf and cubes); I play quite a large variety of games like PES09, COD, LBP and many more although I am certainly shooter orientated.
I had the choice between the the Wii, 360 and PS3. The Wii was what I was going to buy for over a year but then, suddenly, I realised the PS3 was better. I noticed that in the years that I had a GameCube it was rarely played and in just 6 months I must had played the PS2 as much. I do not regret the decision at all, anyone I know personally who has a Wii has then gone on to buy a second console, either the PS3 or 360. And, in my opinion and data, the Wii is just about built up of children's and party games.
As a final note if you have a game that goes online then look out for Bakugekiki!
