Absolutely, we're always looking for new players! We actually play a variety of games, from Battletech and Alpha Strike, to X-Wing, Armada, Starmada, Naval Command, Axis and Allies minis, a bunch of others I'm likely forgetting, and we've recently started playing Gaslands. We're looking at Battletech this weekend, so you're in luck!
We play on Sundays, with people usually showing up between 12:00 and 12:30, with the game usually starting around 1:00. The Battletech games are typically run with each person bringing a force of 6,000 BV each, and we normally don't run custom designs.
Do you have record sheets? If not, let us know what mechs you have, and one of us can print out a force for you. :)
And welcome the forums!
