Mass Effect 3 brought us a backwards game where our choices weren't actually choices but just hollow words.
Walking Dead unfortunately follows this.
My problem with the game is lack of actual choice, as we are forced into certain situations which have a pre-determined outcome.
For example, in a certain chapter (avoiding spoilers here) you come to a critical decision where you have to comment on whether someone is booted out of the group or not. You later find out how this could have been avoided but replaying the chapter and attempting to find a way to prevent a character being booted out doesn't work.
I thought this game would have a good amount of re-playability but it's severely lacking that. Your choices have little to no impact (bar a few decisions which don't actually affect the game). I played through this as an honest man and couldn't really play through as if I were in this scenario for real, so perhaps if I re-played it with opposite choices then certain characters would hate me. However in the end the outcome is the same and that is boring for me.
Having said that this is a gripping and intense game which keeps you wanting more. It can be clunky at times and rather straight forward, but you really care for these characters and want to help them survive.
My suggestion is that you weigh out the choices versus buying the disc or downloading it (mainly cost), but I've seen a fair few people complain about serious bugs so please do some research first.
