I’m also struggling with the itch to go back to ER, busy in a similar boat (around the Haligtree entrance, but it’s been around a year and I don’t think I have the chops anymore). I think I’m going to try and hold out until there’s more info on the expansion.
I just picked up some games from Humble Bundle that I’m going to play while waiting for Unicorn Overlord to release. I think I’ll start on Loop Hero first, but some of the other games in the bundle look interesting too.
