One problem with trying to go for INNACURATE games, is every game is innacurate if you think down deep enough. Hell, you think Axis&Allies handles anything accurate? But then some could say why stop there, why not go and rag on the game Risk, etc. That's why I think it's best to think in terms of... What just was the most terrible?
If one can stretch things and call A&A some sort of wargame, I'd say the computer version (pre-patch) gets one nominee since:
1. AI was absoutely TERRIBLE.
2. Game was virtually unplayable online, despite it was advertised as supporting online.
Actually, I believe there was one Panzer General game that turned out after going gold, the developers realized their online support was non-existant because the in-house beta testing never revealed the fact that all players need to be on the same network & timezone to connect, lol.
