Have you ever played through a game from each generation consecutively?

I'm doing that now, with some special rules to force me to use Pokemon I haven't really used before, with one of the rules being only using Pokemon from that generation.

This is what I'm playing:

>Yellow
>Crystal
>Emerald
>Platinum
>???
>Y
>???

For Gen V, I was wondering whether the differences were enough (been a while since I played) to play both W and W2. I'd stick to Gen V Pokemon in White and use any Generation in White 2. Though, that does mmake it an outlier to the one per generation thing I have going on...

For Gen VII, I could play USUM, but it's got all my latest stuff on, and the differences from SM were minimal... So I was thinking Moon just to save transferring.

Have you ever done this? Any suggestions?
