Yesterday I stumbled upon a very comprehensive review of WFRPv3. The review is particularly interesting since the reviewer preferred WRFPv1 over WRFPv2, due to the sparsity of setting info in the latter. I highly recommend reading it.
E. Long’s review of Warhammer Fantasy Roleplay 3.
Here is the same reviewer with his comparison of WFRPv1 and WFRPv2.
