ok, what do you think is the best naval warfare sim out there? i got a demo of battlestations pacific which runs lovely and looks good, i do like it so will prob get that, but is there any others? maybe a bit more in depth but not as bad/in depth as harpoon? even a sub one? also whats the best global themo nuclear war..."shall we play a game" i quite like the look of defcon, but dont want multiplayer, not sure if its a single player one? any ideas?
