Massively

Tiny Empires is not a craze where you herd tiny avatars, but is a HUD interfaced turn-based game within Second Life. It is based, somewhat loosely, on a feudal society, in which the amount of land you own, or control, relates directly to your social status (although you start as a wanderer and become a peasant before joining the ranks of the nobles, somewhat improbably).

Each turn you gain some income from your land, pay homage to those more important than you and the like. You can also be offered (pictured) the chance to buy more land, sell land, upgrade your technology (dig with a shovel rather than fingernails, use a plough, hire a peasant, buy an ox etc. - I suspect the list continues) to increase productivity from your land, upgrade your house (this is important later on, when to become a king or queen you must have a suitable palace), win prizes in competitions and the like. Oh, and once a year (12 turns) you must pay your taxes of course!

The game is nice in many ways - particularly for me, because you can leave it running in the background and it only clicks turns over every 3 minutes so you can do other things rather than give it your undivided attention. It is completely self contained (although I guess you could swap land for L$) and just for fun - but it is very much fun, and I will be aiming for Princess status just as fast as I can! There are guide wikis, blogs and cheatsheets, and a wide array of in-world groups available already. If you'd like to play and need a liege, come and look me up!
