Darkfall Unholy Wars is an upcoming sequel to the cult classic and niche Darkfall. It's an open world persistent sandbox MMO with free for all PvP, full loot, sieges and the combat is first person/third person with no tab target. This game, unlike the first, will have classes, or roles. You can mix and match roles and switch between with a short timer, so your character is not locked to one playstyle. Leveling one role is easy, shouldn't take more than a couple of days to finish, but leveling them all is hard. All gear is craftable by the player, and you wont be attatched to your items like you are in other MMOs, it comes and go's pretty easy, so losing it is no big deal, and gaining it from others is a nice bonus.
Darkfall has been on Steam greenlight for 2 days, and the entirety of the dedicated hardcore fanbase voted YES, and told all their friends. It will be released on 12.12.12, and possibly released on Steam at a later date, or on the same day, it hasn't been announced. Darkfall Unholy Wars follows the subscription method, you buy the client (unless you owned Darkfall 1), and pay a small subscription fee each month. A hardcore full loot PvP MMO does not fit the FFA cashshop model, so if you can't afford the subscription for a month of entertainment which is the same as one trip to the cinema, this probably isn't the genre for you anyway.
