It’s challenging in a way that Retail is not. And with the launch there are players everywhere in the old game world, so fun. Things are active, things are happening. You’re not running through a town in low level Azeroth as the only player there among static NPCs.
So yeah, this is a fun romp through old-school WoW. Once the fun in this seems to end, I may finally be done with WoW. I hope this can last for a few years, though. I hope Blizzard does something creative with it instead of just following the previous path of WoW development.
