I think I'm just gonna play short or low stress games until I hit game #50 - I've been playing Frogger: Temple of the Frog, and whilst that game does kind of kick my ass, it's short and basic enough that I can just play it for five minutes or until I get annoyed and take a break. Game #50 is gonna be great, one of my all time faves on the GBA.
Playing games has got to be fun, have to take a break if it starts to feel like work!
