I was thinking about starting the WFRP 1ed campaign The Enemy Within but using the WFRP 2ed rules which I believe are much better. We used to play WFRP 1ed before WFRP 2ed was released but we never started The Enemy Within campaign, however now the time seems perfect as we had a 2 year break from Warhammer and we will be making new characters.
Are there any pitfalls I should watch for? How hard is it to convert the game mechanics (e.g. enemies stats) from WFRP 1ed to WFRP 2ed? From what I remember The Enemy Within was a very good campaign and could be worth playing.
