Personally I feel computer games are a waste of time, energy and a drain on intelligence and creativity.
That being said, I sometimes watch my my son play on-line and it is quite entertaining...albeit is small doses.
I think these games are evolving extremely quickly and at times I wander what it's doing to their heads. I think the realism is increasing rapidly also. His new game 'Modern Warfare 2' is insane, it's starting to look very real now and I must also add that they are incorporating much of what is practiced in real life...I wonder where this is all going?!
I went to a gaming expo a few weeks ago with him, and I gotta say, I saw a few 15-20 yo who seemed catatonic and as though their brain was still plugged-in elsewhere. Sad!
Want to see how real it's getting, well the graphics in this clip is pretty much what you get in the game.
