I know there are a group of guys who normally play at Arsenal Game Room. I'm not sure what they're schedules are. I also know of a group that plays out of TCB Games in Huntington. It's a ways North, but they've been known to hold events at TCB Games, Marion as well. Lastly, I know that Saltire Games has been working on Mage Wars as well.
Hopefully you find a good group to play with!
Arsenal is closed down.
I live close to Indy and have another buddy who I play with. Depending on schedules, be happy to play a game or two with ya. Must warn you I am still pretty new to the game.
