It's classic Pokemon, but Pokemon diversity among trainers could be better. (Despite touting 151 Pokemon, it seems like you fight Pidgeys, Rattatas, Koffings, and Zubats all game.)
My team for this playthrough: Charizard, Raichu, Graveler, Haunter, Vaporeon, and Lapras
*Thought I could trade evolve those, but I could only play on DS as my GBA didn't work
