I just found an older review about Tales of Monkey Island which was quite representative for some criticism against TTG in general.
(#1) Episodic gaming still, even with Tales of Monkey Island, does not live up to classic Adventures. Especially content wise.
(#2) Monkey Island ended with Monkey Island 2. (Choice of IP)
(#3) Why make games less usable for PC? In terms of controls?

Not that I'm against TTG publishing any Adventure Games but I hope it known to them that theres more to do. :/
