Does anyone know some seriously addicting RPG or simulation city building games that are free and online?

I've played puzzle pirate, runescape, starwars galaxys, rappalz, and many smaller gay little empire building games but puzzle pirates and this cool space game Territories 3069 are the only ones I truly found enjoyable and I want something else to fill the void in the gaming part of my mind.Does anyone know some seriously addicting RPG or simulation city building games that are free and online?
You might like Creatures 2.. they are little weird looking animals that you basically raise and teach, they create their own little society, have babies, and die. The game keeps progressing even when your computer is turned off.





I'll find the demo for you and post a link!
Oblivion is a great RPG. It requires a pretty good computer to run though. You can download it free online at certain places (BitTorrent).Does anyone know some seriously addicting RPG or simulation city building games that are free and online?

there is a very good one it is called guild wars, it has a pretty boring story line but the graphics are great, its a long time ago sword game, alot like world of warcraft, but it has free online, but you have to go to the store and buy it, and if you do dicide to buy it, buy nightfall, it is the latest versian.
