He was over here all weekend and had the whole entertainment system to himself that day. What would you have done at that age? I didn't literally sit down and watch, but it's hard to miss on a 106" screen running all day right in the middle of the house.
I don't think single player is the focus of that particular game, but it's amusing that you bring that up. Multi player death match games are such a cop out. No story or creativity required, quick to market, tried and true cash cow.
You thinking that 15 hours is some significant time to beat a game *3* times being only reinforces how short and shallow todays games are. I have a Fallout 3 save with over 200 hours in it. Yeah it's one of the few modern games that I can't complain about. But they are far too rare these days, takes too much money to produce when you can just nickel and dime another death match arena game with no real single player story or content. I want more games like that which I can burn a month or two of my life away immersed in another world for days on end, such that I'm disoriented returning to the real world. It's happened a few times on my 360, but nowhere near as much as SNES through PS2 era.
I got my multiplayer shoot em up kick over with Q3A and BF2. It's all the same to me now, done and tired. I prefer huge games that consume my life and take me to other worlds and eventually come to an end, not just sit on my couch and rack up frags for an hour or two. And that goes for PC as well... it's even worse on PC that's why I started messing with consoles again.
