I couldn't agree more. Games lately are more about effects, graphics and cool cinematic sequences. The stories suffer from this and are usually shallow and full of cliché’s. Its so bad in fact that when a game comes out with a even half decent premise its story is raved about as being deep when infact its not.
Adventure games, like 2D games as well, died a premature death. There's plenty of room in adventure games to innovate and expand upon. Plus with the current technology we can only dream how good a adventure game could look and what is even possible.
I just hope the numbers are there for TellTale to continue.
