Some of the best contents for NWN and NWN2 was user made, and City Of Heroes had a lot of good AE stuff as well, so unless it for some reason is less accessible than regular content (eg. extra fees to play) I expect to play a ton of Foundry content :)
I'll definitely be playing a Tiefling as my first character. Always liked the race since I saw the first depiction of one by DiTerlizzi, and I was probably one of the only people in my circle of friends who actually liked what 4th Ed. did with them. I just hope they're viable as greatweapon fighters :)
