Need a good rts game that doesn't make wait too long

Hey. Well, I'm looking for a rts game to play when I don't feel like programming..
Something that'll take the edge off a bit between the hours.

I've been looking for some and alot of the "waiting periods" to do something is usually around 4 -10 hrs. that's too long.

I'm looking for a free rts browser game that doesn't make you wait that long to do one thing. Maybe about 1-4 or 5 hours for somethings sure, but not something whereeas I have to wait 6+ hours to upgrade the town center or build a fleet. That's not cool.

In addition, I don't care if the game is either all or mostly text, I just need a game to break on once in a while, multiple times a day. Preferably, I'd like a fantasy/medieval/adventure type game.

If anyone has any suggestions, I'm all ears :D
