Pokemon Trozei was definitely fun, if you're a fan of puzzle games. I got bored with it pretty quickly (I also wasn't very good, and the "collecting" aspect that would most interest me was borderline impossible), but there's a little more meat to it than with most puzzle games.
Cool. I just wish first-party Nintendo titles would see a price drop. As for the collecting, I've never played much of the real Pokemon, but I think it's just the itch I've been looking for. OCD FTW!
