good point, but i don;t want it to become a rush game ethier, because that is basically what a lot of rts become, rushes. in AoE every game will say rush or no rush *time*. even in starcraft and warcraft, everyone rushes, very few don't and that is usually not because they do not want to, but that they are not very good.
ethier way i can see it being a problem if u get super long 3h battles a lot and boring if u do everything in 10 minute's. but i personally like longer game's then short one's *around a hour ish*
