Yeah I could see this ending up wasting a ton of time for me. Kind of in the same way the mini games were in Red Dead Redemption. You get caught up in playing these little games and realize it's been like an hour. The tennis looked almost like a game on its own. I was going to skip the game and not get any new PS3 games as I await the PS4 but I've changed my mind, I'm definitely getting GTA5.
