Right now I'm available whenever, currently unemployed.
I played AD&D 2E and D&D 3E for a long time but have been on hiatus for a long time. I'm looking for a group again, but I have not played any 5E or Pathfinder, so I will not be familiar with their specifics, but but RPGs are RPGs. Give me a little time and some dice and there will be games.
I also have played the MechWarrior RPG (although I don't know if there are updated rules for that game or not) along with Battletech for resolving large scale combat. Have source books for other RPGs (Robotech for instance) but never found anyone to play them with. Unfortunately neither of those are d20 system games so they aren't here. However if someone has a group thats online for them that has a method I'm in.
