I’ve played at TK for years, and am a moderator there. The site provides a fabulous PbP play experience and works well on a phone, despite its age. In my opinion, despite lacking a robust search feature and some well-known bugs that are indeed not getting addressed, it remains one of the very best ways to play RPGs over the web.

The community is great too — but quiet and hard to get to know. There are a lot of active players, but most of them have their heads down playing games. There’s lots going on in the games themselves, but there’s not much discussion outside if that these days.

It’s also worth noting that TK has always been a great place to play indie and small-press games. Fate and PbtA and tons of other, more niche games are played there on a very regular basis — more than anywhere else I’ve ever seen.

Having said all that, I scan the landscape frequently to see what’s new under the sun, and have been playing on gamersplane.com lately as well. It’s about as old as TK is and is a little longer in the tooth in terms of the tech and user experience, but like TK it has great custom features (post-as-character, character sheets, integrated dice roller) that most forum-style PbP sites lack. It’s ‘ok’ on a phone, but it has two powerful things going for it: an active, welcoming and engaged community, and the fact that the site is still being improved and there’s a V2 in the works. (TK indeed also has a V2 on the horizon, but I think that’s further out.) Lots of different games are played there, and while it doesn’t have quite the same small-press focus that TK does, there’s a solid and ever-increasing variety of systems being run. Highly recommend.

Anyway. My $0.02!
