I have that problem with other consoles, i have times were i play them all the time, then not at all. I havn't played my DS or PSP for ages now that i have a wii. What i say is wait a while. When the online games come out you should get back into it. So get Super Smash Football Charged (or whatever its called) becaus thats online and should get you back into th swing of things.
