I'd love to see more Inventory themed adventures. Sure, Poker Night was shallow but for a $5 game I got tremendous value out of it. According to Steam I played 23 hours of it which is more then I get out of most full priced games.
Even if they don't end up making a season out of it it would be cool if they kept it going, maybe a game at a time, like with Puzzle Agent.
