Lets see here .. Rm or Dm ..
Now Rush3d I know who you are .. And your a friend and all .. BUT YOUR WRONG ! =D .. I started out Dm , I've now played about 6 years of Dm including AoE beta , 5 or 4 of Rm .. I Find that my Dm experican enhanced my Rm into me being able to attack more agressivly. Rm enhanced my econ skills in Dm. They both go hand in hand and improve each other.
As for Rm .. Rm consist of you get a civ , you gather res , if you get a shitty bronze civ you tool rush , you get a good bronze civ you boom and kill. There is Rm in a nut shell.
Dm you start out with lots of res , you make 80-140 villagers depending on your civ. You make econ fast and army fast you rush , if rush fails you gather regroup and attack in non stop spurts untill opponent is dead. There is Dm in a nut shell.
Which takes more skills? Well first to the rook that said HOTKEYS are cheating. That's quite stupid .. I use hot keyz in Rm and Dm .. they are not cheating they just give you the ability to build faster. Ok now back to which takes more skill .. Niether , Rm takes certian skills , Dm takes certian skills. Neither is harder than the other.
They are both fun I advise you to play both and become a true xpert.
