Future Options for Runthroughs

I have some ideas for future runthroughs, I'm about halfway through Shiny Gold X right now, and am beginning my Platinum run. But I may start a third run.

So far I've thought of:
-Pokemon Yellow Something Solo Run
-Rijon X Johto Gym Leader Run (if you dont know what that is, check out my YT channel)
-Super Paper Mario
-Pokemon Emerald Johto/Hoenn Gym Leader Run/Monotype Run
-Pokemon Prism Run

Other suggestions are welcome. Thanks in advance!

I was think of doing a Pokemon Emerald water monotype run. Hmm...

if ya want a challenge, try the no-exp run!
Right now PsycloneMasterY is doin Diamond currently.

Why Don't You Try Yellow Rattata Run?

Do yellow, as the old games aren't done as much nowadays. makes me sad....
