I must confess that I also never really played PoP. Most of my time went into ACOK and Floris.
I have never played that mod as well. But saw a random "let's play" on youtube and I feel it might be interesting to actually give it a try.It's glorious, that's all you need to know. People who made it were genius modders!
Is it really that good? @MadVader - or was it just a touch of sarcasm on the usual "modders will save the world drama"?
