had my first Next session. I have one MAJOR complaint. At first level the players are walking through every encounter... it was too easy, they killed like fourty goblins and an ogre in the same day without even getting bloodied. I wasn't easy on them either, I setup ambushes, decoys, surrounded them, sneak attacks and pretty much every sneaky trick a goblin could think of to no avail... and a sling should not do a d8 damage, I'm assuming(hoping) that's some sort of halfling racial ability. Besides this it was loads of fun, loads and loads of fun.
I wish I could comment more on the spell system, but my wizard got drunk and said, Sleep is awesome, I'm memorizing that x3. It actually worked out really well for them... but nobody wanted to play the wizard. Oddly enough as half my players are 2nd ed. players and the others from 3.5
