As for pokemon, i love the 'structure' of the game mechanic, but maybe because i grew older i wanted more 'mature' pokemon like series,

the alternative, shin megami tensei series and all of it spin off. It have the god/godesses and mythology that you can have as your monsters and go

collect/fuse/create them all. It's fun and satisfying also it's and rpg and more 'mature' theme. Pokemon got it own fanbase and i know it's a fantastic game,

we all have 'some' game that we attached to and consider the best game ever.
