Do you also happen to have played the whole series from operation flashpoint onwards? .. after all those years, finally a really nice i44 release. Sure their demo was nice back then in OFP, but now it finally feels and looks.. and not to mention sounds, the business, in ArmA2
As for naval warfare also don't forget the Silent Hunter series either, in their kind they are the best. 3 and 4 at least, not 5. And there's a few nice mods making surface vessels playable too, able to fight properly with them as well, for example. And tons of mods and tweaks and addons about for both.
For aerial combat, the IL2 series reigns, no contest there. The new Cliffs of Dover release in that series is quite good, albeit in need of some patching, even with some updates already applied.
