Not worth the price, trouble or time. Unless you laugh at the many many many glitches still around this is not fun. PC version is barely ok to play without the progress-stopping glitches plaguing the consoles versions. I played over 20 hours trying to get over 1 mission because my save was corrupted along the way. I couldn't get a refund. Buyer beware.
Is it value for money? NO. IS it as inmersive and story driven? NO. Does it have a Great twist? NO!! It is artistic and interesting but not enduring nor surprising. Could have had quite a few more npcs with stories but didn't. Felt more like a test than anything else. Classic case of art over substance. Get it on sale. Don't bother otherwise. I completed it in 3 hours whilst I was doing laundry. I wont have a second playthrough for the achievements.
