I give it a 7. The game was indeed enjoyable with some surprising and memorable moments, however, right from the release of the 2nd episode (steam user) I have had technical issues with choices not carrying over properly from one episode to the next. Each episode I played seemed to want to generate random choices for me even though there was no option for this when i started the episode, it just began.
When i thought i finally had the issue fixed, all of my save files no longer appear in the screen and now the system wants me to start the whole game over complete from scratch even though i have several save files in my documents folder as well as the pref.prop file. This has been my most dissapointing moment of this series. It's just too damn buggy.
2ndly, choice does infact NOT matter. Nothing u do will affect the outcome which was my understanding with "Choice Matters". The only thing choice did was influence Clementine, mold or shape her. But then you don't get to see how these choices are carried forward for clementine.
So, in the end the game was enjoyable, however several aspects of the story just don't add up, such as clementine dragging a 180 pound adult through a horde of walkers to saftey. 1 of many things i found that just don't make sense.
