Titles from franchises I like, for example Zelda, Metroid, Kirby, Final Fantasy, and more, as well as possible first time entries, like Devil Survivor and Monster Hunter, and then of course pick up all the DS titles I missed (never had a DS) like the two Zelda games. Also, not just titles that were/are confirmed, but future titles that might peak my interest.
"I don't think this is funny. I wasted my time entering." -GameFAQ's new slogan.
