I liked No Mercy well enough, and same as you liked VPW2 more. The logic setting were in No Mercy too, you just had to use a GS to access and modify them. I also liked WCW Revenge and World Tour. They were fun. But they don't quite compare to the Firepros or KOCs.
My first Firepro was Firepro Wrestling G on the PSX. I loved the Victory Road story mode in it.
