YES FINALLY SOMEONE WHO SHARES MY SENTIMENTS!There are plenty of RP genres that I see more of than I'd like due to my disinterest in them, but there's clearly a demand requiring a supply so I hesitate to call anything "overdone".
Underdone on the other hand... I gotta agree with the people above saying sci-fi, clearly a demand not being met here by the sounds of it (don't look at me for help though!). I'd love to see more historical roleplays (except for ones just about (European) royalty, not a fan), alternate history roleplays, and roleplays that focus on a variety of cultures (be they real or fictional)
I so badly want historical RP's that are not about European royalty, WW II, and all those other way overdone topics. I also love exploring other cultures and not a lot of RP's focus on people outside of North America and western/central Europe.
