I've got a 1.0 version ready to go for the next time I feel the itch to play Dark Souls, but haven't given it a try yet. I've even gone so far as to build a character for when I decide to.

A few other changes - infused weapons like fire and lightning did much more damage, famously, the Ring Shield's attack was based on your weapon in the other hand, and could do BONKERS damage, DWGR activated at 50% load instead of 25, so flipping havel moms was a thing, and aggro range for most enemies was toned waaay down. Also, boss drops that are automatically put in your inventory like the Leo Ring were actual drops that were missable. It was a crazy time.
