Why limit it to just role-playing games? I know that RPG players have to struggle quite a bit to find other players, but as a board-game player, I'd like to see some other dense games on here like Gloomhaven or maybe some trading card games like Magic: The Gathering.
Oh yes, if you're going to expand on this, it would be great to include basically the range of games you typically see played at a local game store. This would span card games, board games, RPGs, and tabletop miniatures games. There's good resources out there for finding what titles are in demand. Boardgamegeek is a good one for board games, then for card games and miniatures games, any employee at a game store not called Games Workshop could give you the short list of titles to include!
I think board games are different from RPGs, though. Like, "Ticket to Ride" is a popular board game, but there isn't really a TtR community that's specifically looking for recurring sessions with other TtR players. It's more like there are board-game meetups that rotate through different games each time. (At least, that's been my experience at my FLGS.)
Games like Gloomhaven, which another poster mentioned, are a different ball game -- more like RPGs in that respect.
Great question. I chose to focus on tabletop RPGs because I wanted to focus on a niche I was personally familiar with. I'm bullish on the future of the space and would love to build tooling for game masters if the site catches on. That said, if those games are something you're interested in using Roleplayful for, I would be happy to add them.
