It's nice that Telltales publish walkthroughs for each chapter released, but with a walkthrough it's a tad too easy to spoil more than you actually want. Therefore a hint system would be better..
Such as the "Universal Hint System" -> http://www.uhs-hints.com
Here's an example of chapter one of Tales of MI:
The Universal Hint System is updated by gamers themselves (as I understand it..), so it's not released at the same time as the games are.
It would be great if Telltales could do something similar...
