First of all, see if you can trade that THPS3 away.
That game gets so old because of the frustrating camera angle. But I guess if you like the game, keep it. Also, make sure to get Advance Wars. It'll last at least 100 hours if you like strategy games. With occasional breaks I could play that game for hours and not get bored of it. There are so many modes and once you complete all of them, you can design your own maps, and battle friends. Usually it's pretty hard to find someone that knows how to play though.
