SEGA’s ambitious free-to-play MMO, Kingdom Conquest [Free], a title that combines dungeon crawling and the city building of a traditional strategy game, is now available in the US. The price is, of course, free. Cost factors in via the purchase of Charge Points, which is currency that can be used to speed up resource gathering or to buy little bonuses us non-paying peasants in the world don’t have.

Let’s talk a bit about features, eh? Kingdom Conquest will allow you to team up with up to four other dudes on Edge, Wi-Fi or 3G in the dungeon crawling portion of the game. In these dungeons you’ll be able to collect your standard fantasy fare and you’ll be able to unlock over 100 types of monsters. You’ll then be able to trade your loot with others if you so desire.

The strategy aspect, the city building, is a more solo-ish affair that’ll have you building up a kingdom, forming alliances, and creating armies that can stomp other armies. The junk you get in the dungeons can be synthesized in some sort of crafting system for use in this portion of the game.

If you need a pal to play with, hit up our forum thread on the game. There are a couple of dudes in there looking for some playmates. I should note though, that according to a couple of user reports, you can solo this game. But like World of Warcraft or whatever, it ain’t going to be easy as you progress.
