I disagree; the RAF tech tree is overly simplistic. For example, Greece is made up of the following: 1 swordsman, 1 spearman, 1 archer, 1 horseman, 1 super-spearman and 1 boat. The first 4 have 5 upgrade levels and 3 unit appearance changes, the super-spearman (spartan) doesn't change, and the 1 boat has 3 upgrade levels. There's also a catapult and a flame thrower siege thing, I much prefer the variety available through the AOM techtree, though certain elements of RAF are very good: the ladder teams, the walls, the large boats, the large armies and the way formations work, etc. Definitely. The economy is overly simplistic in RAF, and this is something which detracts even further from the game due to the simplistic of combat-unit choice.
