Why don't you just give the bullshit a rest? I mean honestly, whose intelligence are you trying to insult here? Or are you just thinking of a completely different game or something? Either way, admitting your mistake would save more face than bullshitting.
The RAM requirements are stated on the maps, and yes that includes the number of units that could be battling it out. From what I can remember, the core game never demanded more than 64MB for any one map. The 64MB maps were huge.
2GB would not have been found outside of servers. Even Silicon Graphics rigs didn't have anything like that and those were for heavy duty rendering. No game would have demanded that. Not one.
