| Ka-pi96 said: Generations used to be by system too, gen 5 changed that so it seems that was coincidental rather than a rule they were following. No reason this can't be as well. |
No, they weren't. Gen 1 and 2 were all Gameboy games, just like how Gen 4 and 5 were all DS games. Only Gen 3, and likely now 6, were exclusive to one system.
