I'm a DM/GM and has been so since age 19, so that would make 18 years now.
I'm most of the time the Master, but I sometimes like to play as well. (A rest is well deserved).
We have a constant group of players for the last 14 years (We could say we are family now), we played all type of campaign and game systems, and we are always looking for something new.
Sadly, they are left behind in Argentina and we are meeting online (mind the time difference) but I'm also looking to start something up locally as well.
I've mastered and played many things:
Warhammer Fantasy 2E.
Warhammer Fantasy 3E.
D&D 3e.
D&D 3.5e.
D&D 4e
D&D 5e
Pathfinder 1e
Star Wars FFG Version
Lord of the Ring (The red book)
The One Ring
G.U.R.P.S.
My Little Pony (Just for my kids

Name: Gustavo
Age: 37
Place of residence: Rotterdam Centrum
Games: too many to mention
Type of game: If it's a Roleplaying game, it is good

Days: Afternoons or Weekends (Prefer afternoons to leave weekend free)
other info: 3-4 players prefered. I like mastering long campaign, but we can do shorter adventures, or one-offs depending on the commitment of the players.
