I've bought every single Telltale game since Sam and Max Season 1. I don't understand Strongbad, Wallace and Gromit are cute, but I won't buy another season of either of them. Monkey Island did reduce the Sam and Max craving a little (I will buy future episodes!), but I MISS SAM AND MAX!!! PLEASE make some announcement that you haven't just given up on them. I remember a poll on this site about what game was the favorite, and Sam and Max won by a large margin.
I'm not saying that you should give up all of your other series (although I wouldn't be upset if you gave up at least one of them); just don't forget what got most of us interested in Telltale Games to begin with!
