I agree, this show is quite cool. I've seen it once, and I would watch it again if I saw it on.
However, one thing strikes me as odd. The Rome: Total War engine doesn't really look that impressive in my opinion. Yeah, there are a ton of units (obviously the coolest part of the engine), but beyond that.. nothing strikes me as very impressive. The character models are iffy (certainly because of the huge number of troops, but I'm just saying.. I know they can't look Soul Calibur quality or anything), and the animation was pretty laughable at parts. When shown from far away, the game looked very cool, I'll give it that. But once zoomed in at least a partial bit, it looked.. eh.
But now that I think about it, no full 3D strategy game has really impressed me graphically. I mean.. this one looks pretty decent. C&C Generals looked pretty good, I guess. Same with WarCraft 3.
Regardless of that, from what I've read/heard, it does seem to be quite a fun game though.
