This is the first part of my collecting of Oldhammer books. You can see from the corners that these books have seen a lot of action, although incredibly my Slave to Darkness copy still has its dust jacket 25 years later! In fact, I believe I got Realm of Chaos originally as a supplement for WFRP. I was also playing a lot of Warhammer Fantasy Roleplay at the time, and the two mixed really well together. I started playing around 1989-1990, a few years before the 4th edition came along, and although I played a lot of the 4th (High Elves vs Goblins, anyone) the one which made an impact on me most was definitely the 3rd.
The 3rd Edition really is the edition of my youth and the one that represents most Oldhammer to me.
