We just (10 minutes ago) finished playing a round of Quake 2. Some games are streamed (https://www.twitch.tv/thfrw/videos/all | https://www.twitch.tv/communities/openbsd_gaming | https://www.youtube.com/channel/UCF2MeFBWJoFZtz0ADX3Us0Q/vid...), we even have some more modern FNA games and a list of games available on GoG for the platform (https://www.gog.com/mix/openbsd_engine_available). We generally hang out on irc #openbsd-gaming @ freenode.
