Here's a classic that should be in most collector's libraries alongside the other versions from the second generation of Pokemon games, Silver and Crystal. Like the previous three versions, underneath its cute exterior lays a strategic challenge unlike any other, one that is certainly worth taking on regardless of how old you are. The AI is improved from the previous generation of games, making for tougher battles and requiring players to come up with new strategies; two new Pokemon types, about 200 new techniques and 100 new Pokemon prove that you can teach an older dog new tricks. Too bad those tricks couldn't get transferred to Red, Blue, and Yellow. I haven't played this game in some time, but I believe that my Pokedex is in the range of 175-200 species. A remake of Gold, Silver, and Crystal for either the GBA or DS couldn't hurt.
