I can honestly say, I think last night was the first time in at least ten years that I played a video game for nearly six hours straight. My son and I went out earlier in the day, and picked out a new PS2 game, Batman: The Rise of Sin Tzu (With free collector's action figure!), grabbed a 2nd controller, and whiled away an enormous amount of time.
I got a little tired of beating up bad guys after a while (and we still haven't finished the game), but it was a load of fun, and I spent a lot of time beating the tar outta baddies with my son. For the record, I was Batman, and he was Nightwing, though we switched off a few times.
Near the end of the evening, my daughter played a few rounds on the level we were having trouble with ("Protect the Doors to the Batcave!"), and honestly, even at four years old, she did nearly as well as me once she figured out the controls. "Kick his butt!" She often cried out.
Yes, guys, this will be one to look out for, down the road.
