So this is technically a new release, but Pokemon Ghost Grey. I think it's the best romhack I've played in years. It's so creepy and really shows off how Pokemon's Gen III engine can really work for item-management survival horror. Lots of great psychological horror and dystopian themes. The protagonist looking intentionally different in his/her metagame character portrait vs. actual mirrors and photographs is, um, relatable 😅.
Oh, Summer is the best rival too.
