After playing Starcraft for such a long time with friends, we found a nice game online. You raise an army out of four races (human,dwarf,elf,orc) and train offense,defense,spies,sentries ect. as you strive to get gold and upgrades. Very challenging early on, but it gets easier once you can simply attack people.

Oh and if you do join, it has a very nice setting where you can set someone as your commander. This makes you an officer of a commander, and the commander's job is to help the officers out. Every two soldiers the commander gains, each officer gains one soldier. If you feel like it, you can message me and I'll clarify to my commander that you are joining. Me and my starcraft buddies have a little group, CrAnkY is our leader so have him be your commander if you want to be with us. Or me, but Cranky is much better and he's one of my online friends in Starcraft. Goodluck if you join! My account is TundraWolf.
Edit:
How can I be so silly! There is a "clone" of kings of chaos, which in my opinion is better,easier and not even finished being processed! It's called DarkThrone and they are beta testing right now, its fun as heck. It is a lot easier then KoC (Kings of Chaos). Me and my starcraft buddies also play this, but we haven't established an alliance yet...

I'd also like to mention these are free games, and don't require any really good video/anti-lag stuff. I'm not sure if DarkThrone will have graphics when its done, seems to be taking them a long time to "finish".
I suggest reading the instructions or help sections if you begin to play, if you don't know what you are doing you might do something dumb =) which we all usually do at some point...
