Panzer General is its predecessor but PGII was much better.
There is a newer game called Open General which is unbelievable.I've done a little beta testing for Luis Guzman with Open General.He's a great guy and genius IMO. If your interested, I've posted a link to his site for anyone with PGII to catch up on.This new system has it all, every time period of war there is can be played in this new OS.The graphics are the best available to date bar none.The suite editor is unlike anything you've ever used before.I can not say enough on whats being developed by this gentlemen.Its still in beta testing but can be dl'ed and played in its current state of development and is free.
Check it out for yourselves.
Cheers,Pointman.
