Great answers. Thanks for the quick response. Just in time for Christmas!!
I've got all the Combat Mission games and I would say only they are in the same ball park for accuracy and support.
I primarily want a game (sim) that I know I can play for years, isn't full of teenagers on MP, is relatively accurate, receives continual support, and is enjoyable. Dangerous Waters had the potential but support wasn't there.
Graphics are good enough. Tactics and accuracy are what I feel are important.
