Colosseum and XD- Great games, but I wish people saw the charm in them more. (Plus, I would like to see a Miror B. reference or something.)
PBR- I might get this game. Back in it's release, it was just not really worth the $50. However, it does the "battle frontier get-up" fairly well with very original ideas.
Box- Harshly expensive. I go to a video game store that offers it for $150 (for a copy they actually have), and they don't mess with prices. The problem with this game other than price, is that since new generations allowed transference rather than trade, the use for this dwindle.
My Pokemon Ranch- Same but different problems. It stores just for Diamond and Pearl (Platinum expansion only in Japan), but its use hasn't went down as much as Box (considering that there are no 5th gen storage games yet). It's ten dollars;you get a Mew. What was the real problem with this game? Sometimes I even enjoyed seeing what my Pokemon do.
Pokemon Channel- People criticize this game (like G4) and don't realize the target audience. Other than PAL Jirachi, this game looked fine for what little of a game it was supposed to be.
