Never played much Undertale, but I do enjoy me some Sonic Adventure from time to time.
As for other game progress:
I’ve finally recompleted Megaman Unlimited start to finish. Both campaigns and the extra boss.
FF4 After Years I’m kind of halfway through. I’ve beaten Ceodore/Kain’s tales, beaten Rydia’s, beaten Yang’s, beaten Palom’s, and am now grinding on the last one.
I always make sure to grind to a decent enough level after beating the tales so I can prepare myself for The Crystals/Planet Eater/Final Tale. Running through the challenge dungeons and getting some extra equipment definitely helps.
After that I have Edge, Porom, Edward and Lunarians to get through before I can officially start the endgame of FF4AY.
Persona 5 I actually haven’t touched in a DANG long while, same with Battle Network 1 among a few other games.
I plan to continue the postgame of Megaman Starforce 3 when I get the chance to. Haven’t touched that in a dang long while. Not to mention I might wanna grind for Wolf Noise so I can have higher Link power if I can get more brother bands with people.
