in my imagination the Perfect Game.

what should be in it

the 3D map
the era changes
MTW's glory campaign (the one with the points)
Marian Reform type of things that affect unit and stuff (not only bodygaurds)
RTW graphics or better
all kind of Final Touches
Campaign save replay
Battle simulator
NOOOOOOOOO BUGS
More Historical figures (they were in MTW but they're missing in RTW)

more just post it
