I'm currently deciding whether to do another run of Crystal VC or HeartGold (mainly because 13 years on I'm still pissed about what HG/SS did with Eusine, not to mention I'm not very fond of the redesigns for the Johto Elite Four). In the meanwhile, however, I'm looking for and playing fangames that are direct sequels to G/S/C or that show a future Kanto/Johto. Unfortunately, there aren't many, so I'll have to do with what's available for now.
I recently completed the main game of Xenoverse and just started a second run with a different starter. I have... extremely mixed feelings about that game and its plot, but I decided to have another laugh with it, enjoy what's actually good about it, and see what lessons I can learn in case I decide to take matters into my own hands and make a G/S/C sequel myself.
