Sundays are best for me, but I can also do weeknights (Tuesday, Thursday, or Friday, currently). I live in Dorchester near Mattapan, but I'm able and willing to travel as far as Somerville, Dedham, or Braintree.
The RPGs I know best are D&D, GURPS, BESM, and Cinematic Unisystem, but I'm willing to give many other systems a try, too. I usually prefer fantasy, and have played quite a bit of horror (though I'm a little burnt out on it at the moment). I'll play occasional SF games if they grab me enough, but I'm not really into supers or cyberpunk.
If your group has an opening, please let me know!
