"Persistent online war being fought by thousands of players." Ack. You had me excited there for a moment, but I think I'll give this one a miss.
As it turns out, I am rather fond of your idea 2 concept, and I share similar dreams. I was thus excited when screens for the game 9th Company: Roots of Terror
appeared showing first person action, as well as implying an overall strategic layer and RTS-style tactical command. Unfortunately, all of this was a false hope, and the result of Western web sites such as 'Rock, Paper, Shotgun' accidentally labelling screens from the Russian FPS game The Truth About 9th Company
as belonging to 9th Company: Roots of Terror.Raven Squad
was supposedly an RTS/FPS hybrid, which is in theory somewhat close to what you describe, less an actual strategic layer. Alas, the game sucked.
This genre is basically empty, although by the looks of things, Graviteam's upcoming tank sim Steel Armor: Blaze of War
combines both a tank sim with the tactical and operational gameplay of the Achtung Panzer
series. Although it is not strictly like what you describe, it is getting there.
