I'm thinking about beginning to save up for a next-gen system, but I can't decide which one. I'm not real crazy about online, so that's not much of a deciding factor. I mostly want a system with good single player action games and shooters. The Wii is fun, but it seems really light on the serious single player games. Seems more like a party system. The XBox 360 is cool, but I don't have any Xbox stuff (currently on a PS2), so I would be starting off from scratch. It does however have some games that interest me. I'm also intrigued by the hd drive. The PS3 seems really cool and I love the graphics. It has some good games, and it has some interactivity with my PSP. However, I'm not sure about the Blue Ray format, I'd hate to get this and some movies if that format is just going to die. So, any suggestions on which system I should start saving for?
