Planet Battleground

http://www.planetbattleground.com/recruit.php?id=8478

Setting: C&C, Choices: Russia or USA

My second favorite, I've been playing since their Game 2. Requires some clicking, but the built-in Recruiter is now limited to only 10 clicks. But there is a Bank, an experience system, not much else too complicated. No build in alliance system.

LordsOfLegend

http://www.lordsoflegend.com/

Setting: Fantasy, Choices: Humans, Elves, Dwarves,

Orcs, Trolls, Undead, Dark Elves, Draconians, Fangolians

It's sorta complicated at first. There's a building tree for what you can get, and limits for personel. Sorta like playing an RTS game without having an actual map to play. There is a built-in alliance system, but there's no clicking in the game.

DarkThrone

http://www.darkthrone.com/recruit.dt?uid=V30260R30226E30311R30362C30379X30277

Setting: Fantasy, Choices: Humans, Undead, Elves, Goblins

A more complicated version of KingsOfChaos. Different levels of upgrading soldiers and buildings, mercenaries, and other things. There's all kinds of options here, built-in alliance system, there's a built-in Recruiter and clicks are a must.

NationStates

http://www.nationstates.net/cgi-bin/index.cgi/target=display_nation/nation=dun_huang

Setting: Political, Choices: Various things for your nation

So this is something quite different from the rest of them. There's no attacking, no gold, no real symbol of wealth. No goals really but answer political Q&As, driving how your nation will develop. Are you driven to provide all services to your citizens? Do you want to give money to special interests? Are you promoting democracy or ruling with an iron-fist?

Some of us are in the SWR region, if you want to join. Overall, its pretty simple and interesting for those politically (or not) inclined
