1) There is a patch to 2.7 to 2.71?
2) RoM standart map is bigger than Civ 4 original standart map?
I like to play Earth maps. I played standart earth maps with 23 and 12 civs, but both in late game are so slow (40s to change a turn, it's boring). My pc: Pentium D 915+, 4GB, 7900GS 256MB. In original version, it's not so slow. I tryed playing without revolution mod, helps a little.
3) There are earth maps smaller than standart in 2.71 or future versions?
4) Naval units can't do ranged atack like siege units? My naval units just can bombard city defenses. Battleships should atack land units for exemple.
