I've played this game almost more than any singleplayer game (probably tied with Morrowind).

I've been playing Rome a lot lately, and got to thinking how utterly, completely, totally PERFECT any game would be, as a MOM/RTW hybrid. Think about it. On one level, you have a TW game, with all its tactical/terrain considerations (that MOM tended to lack, with necessarily featureless landscapes). The units for MOM mostly have TW counterparts (with the exception of heroes, flying units, and mythical/summoned creatures), and it's easy to picture a MOM sans magic (without which it would still be an awesome game) in the Total War style.

On top of that, you add a whole layer of MOM, the ludicrously in-depth magic system. The global/map/unit/combat spells would apply very well to the current campaign-map approach for RTW: You can focus on unit enchantments and simply buff up your "normal" armies (flying halfling slingers anyone?), or use summoned armies of fearsome creatures, or rely on overland spells (raise a few mountains around your cities, sacrificing farmland for defense), or all-powerful-but-draining global enchanments. I can just imagine being a necromancer again, and casting that global spell (forget the name) that makes every killed unit on the map rise again as ZOMBIES under your control. ARISE MY ZOMBIES!

I'm not even going into the strategic implications of the dual worlds. Anyway, I've just described my dream game.
