I agree. While the telltale adventures are not all terrible, there are a lot of other adventure games I'd recommend playing first.
I'm playing through the Blackwell games at the moment, for example, and they are fantastic. Great story, simple yet rewarding puzzles, great characters, great music.
I've also heard a lot about Gemini Rue, which I'll play soon and the Syberia games which I picked up this weekend. Then there are all the classic lucasarts and sierra games etc. etc.
You could pick up a ton of these game from gog for less than that bundle of mostly average to crap games. You could probably wait for a steam holiday sale also. If i remember correctly they were selling all the telltale game for a similar price.
What was it about BTTF you did not like?
It was intensely boring. The story, the characters, the puzzles and my goodness, the dialogue. It was all so bland, I just had no desire to keep playing.
I don't know if I'll ever go back to it and try and finish.
Hector Badge of Carnage is an awesome adventure game.
It was one of telltale's better games, however, it was completely and utterly filthy. I didn't expect it to be so disgusting.
