Yea I kind of agree with the EE2 vs EE1 opinions. The EE1 gameplay was just better overall (more epic, options to mod units to tactical doctrines, better balance between tactics and strategy). EE2 looks like they said RoN is the wave of future, and tried to shoehorn EE1 into the RoN mold, when really RoN just feels like a quickie alt-Civ to me---lite junkfood that's only good when you're really hungry or don't have time to cook. At any rate, not what I think people want in an RTS, which is lots of units, lots of tactics, dominating over the base-building/management portions.
EE1 with all the doodads of EE2 (the crowns, weather, the battle planning with the AI, new buildings, less linear campaigns, etc..), a facelift, and true 3D terrain (at least like CoH) would be stellar.
I'm pretty sure EE3 didn't approach that goal (though I never demo'd it) as it quickly flopped.
If you do restart EE2, I recommend running the expansion, and also giving some of the campaigns a whirl. The American, German (teutonic), and the Masai/african campaigns were all fun and challenging.
