Dig diggity dog. WWF No Mercy is my most-played game of all time, and nothing else really comes close. (There was a six-month period in my life where I played literally nothing but this game.) Late Attitude Era is my wrestling comfort zone, and the AKI engine is the only half-decent take on wrestling mechanics in video games (outside of the Fire Pro series), so it was a natural fit. The thing that elevates this game over WCW/NWO Revenge is the Create-a-Wrestler mode, which turned it into a dream match machine. Still one of my favorite games to pop in and revisit every now and then, though I mostly stick to Fire Pro World these days.
This and VPW2 are equals in quality but for different reasons. VPW2 has a more in-depth and methodical match pacing but a balancing issue in where MMA guys become overpowered. This game has a faster pace and very fair AI but makes submission wrestling harder because of the fast crawl to the ropes so Benoit, for example, ends up at a disadvantage. Still, as close to perfection as we have gotten with a wrestling game yet.
