It'd take an age! So let's say you've done a complete run through so you can hit skip on those scenes that don't change (which would still leave a lot I guess). But say 15 minutes for the other 115 walkthroughs as an average for each chapter (some are shorter like One and Two of course), but then we have to add in time for the specials which have their own paths (didn't even include those!), so the VR game has twelve different runs itself. But let's stick with 15mins for giggles. 15 x ten chapters = 150 mins x 115 (for you've done one) = 17,250 mins or 287 hours (I've also excluded bonus material, easter eggs etc).
No one is going to spend nearly 300 hours playing this surely?!!!
