Wow. I'm surprised they'd drop it. It's not like we're talking about some obscure piece of crap here. Troyes is in the top 50 and would probably be ranked a little higher if the iconography wasn't so scary to newbies. You can play it on BGA as well, where it is wonderfully implemeneted. Really surprising.
It's really weird. Either they gave up on a game that didn't earn them enough or there were some license issues between Z-man & Pearl Games.
