After being massively in love with the original game (first Steam game I get 100% achievements), I just started a new save. So far it feels mostly the same amazing and self-guided experience, just a bit deeper, so I'm not people who hated it at launch will change their minds now.

I hope the current coop "lite" gives way to true synchronous coop. If that happens, I think I might never play another game, ever. ;)
