Command & Conquer

im sure there is, PLENTY, just check online for low ranked players :P

I suggest that you first play the Campaign Missions and think of them as a basic training tutorial. They start off quite easy with only a few units available, then the missions progressively get harder and where you then have access to more units. Think of this similarly in what you experienced when you first played Generals and I feel you started by first playing the Campaign Missions and at first you only had access to a few units. Similarly so in Red Alert and where I think its best to first to get to know all of your units strengths and weaknesses, and this in a gradual fashion which occur within the Campaign Missions. After you have gotten to know all of your units to a basic level then that would be a nice time to start playing with others so that you can start learning some more from others.
