Well, there are so many to choose from, but I guess I’ll just offer some of my favorites~
If you’re looking for stuff that’s pretty much finished, and if you don’t mind furry stuff, you cannot go wrong with Noone’s game. It’s a few years old, now, and it’s not still being developed, but it’s still one of my favorites to date!
Something I’m following loosly is this unnamed RPG, though I haven’t been able to play it recently because I’ve been helping to run a little RP server born on this site.
As for upcoming stuff, you should be on the watch for Juni’s Appetite, which should be out soon!
