my least favorite Pokemon game was by far heart gold/soul silver. mechanics and graphics were a huge upgrade from gen 3, but trying to get through the Cynthia's team was nearly impossible. Starting off with the spiritoumb, the thing had double team was (for me) the hardest part of her team. For me a little challenge was good, like in b,w,b2,w2 where you could change the difficulty of the game, but that dang team was so well designed it just made me want to go:boom:.
