My brother, who is around 30, subscribes to the generation behind theory. Basically, you just have to have the willpower to only buy consoles and games that are a generation behind to save money. His best love is the Dreamcast, but he recently bought an X-Box but is now getting rid of it for unknown reasons. He is considering buying a GC, but I told him he can borrow mine anytime to save cash and system redundency. Anyone else subscribe to this theory? I can't say that I could do it.
Also, I am considering going half and half with one of my brothers on a Wii.
(Assuming they would be interested, which might be too great of an assumption) If you trade off every couple of weeks, you'll be more likely to want to play it when you do have it, plus your game collection will obviously increase faster. And if you or your kids get to addicted, it would be a good break, ha ha.
