Well, Saturday is a bit of an open games club. For the last two weeks, I have broken my extended hiatus as a GM/DM to run a new D&D 4e game. It appears to be going OK. I'll be playing 2e this week myself.
Fridays, I'm often gaming at a friend's flat. Here, we've been playing The One Ring RPG and it is really cool. We've got two games going from the same GM. The main game is a mixed bunch of races on a cross Wilderland series of dangerous quests and the other is about a bunch of Hobbits who go for walks, play that wonderful game called cricket (though there are more breaks in play, not just for Lunch and Tea), drink beer, smoke assorted varieties of pipeweed and accidentally fight a Warg.
I also play historical wargames from quite a few eras.
