New World is currently the last stage of beta access, which can be joined simply by pre-ordering the Steam version (if you order the Amazon version you have to wait until full released) of the game. I'm about 30 hours in so far over the last couple of days and find it to be an interesting and more enjoyable spin on the typical MMO style.
Some of the larger aspects are more traditional MMO such as dungeons with specific mechanics to figure out, quests and tracking, faction and territory control; though there are a few aspects that I find make it different.
There are a lot of things I'm probably forgetting currently due to having just woken up, but so far having a lot of fun with this.
There are three main factions, with the ability for players to create Companies (aka Clans or Guilds) to band together. The factions are as follows:
Each faction can buy territories and hold them based on their ability to actually hold and defend various forts. If your faction owns a territory, you get special bonuses and access to certain perks within those hamlets and forts.
