>>47070345i really hate when people say this. Yeah, a big point was to show off pokemon in 3D, but more than that the games function as these massive battle towers. Just hours upon hours of nothing but battles for you and the rental pokemon/equal levels actually makes a lot of the fights require you to use your brain and not just mash A, which sub sequentially makes for a really enjoyable experience that's superior to even the real battle towers.
I do think it's pretty irrelevant now though since there's showdown which basically fills the same niche except better since it's real people not AI.
