I stumbled onto a game called Visual-Utopia not too long ago and within the first couple days, I was addicted.
Heres the link,

( I promise it's not riddled with viruses or some raunchy porn site )
It's incredibly easy to learn.
It's a MMO/Turnbased mix where the game progresses on turns called "Ticks" that happen every hour. Each action takes a certain number of ticks (building, training troops, moving armies).
You pick between 6 races ( I believe?)
You can play the game by yourself or join a Kingdom (recommended, it's just great teamwork)
The game focuses on,
resource management
city placement and building
city construction
Troop training
Troop movement
War!
( These are just SOME of what it focuses on, theres a bunch else )
In any case, I recommend you check it out. I'm looking for new friends to play with!
I'm not a spam-bot, my name in the game is Thickwilde ( find me
