If you're interested in playing TPA in a league, you're always welcome to join my facebook pinball club. We play leagues with the games: The Pinball Arcade/Stern Pinball Arcade, Zen Pinball 2 and soon Pinball FX3. All you need is a facebook account.
Just search for "The Pinball Arcade/Zen Pinball 2 Official Club", or use the direct link to our facebookpage: www.pspinball.com
I've set pretty much all the high scores I wanted... Got bored of all that grinding but I play now and then some of the Facebook tournament tables. Been playing Dark Souls 2 so haven't got much time for Pinball Arcade anyway
