Other than a couple of random crashes in early chapters, the only error I had was that achievements didn't work for episode 1 for me. Managed to transfer saves between PCs (upgraded after Ep 1) wiout any issues. I'd assumed all the save woes were console...
No problems with it for me either.
Was I the only one to never get a single save game error on the PC version?
I wish I could say the same about some episode 1 audio issues and I had some graphics taking a while to turn up in a different episode too.
Hopefully the success of this will get Telltale to finally build a new engine!
