Then there is a better option. Minecraft.
Minecraft is an indie game that is released.
It's world size dwarfs the size of Darkfall Unholy Wars world. Rather than taking a few hours to cross, its' so massive you'd probably never be able to cross all of it. Mathematically it is over 9,000,000 times the surface area of Earth. 4.7 Quadrillion km2. How many square kilometers does Darkfall's world have? Some forums posts indicated the largest size of the whole area was 250,000 km. This means that Darkfall's map is actually 0.0000000053% of the size of Minecraft's playable area, not counting area to build above and below ground, alternate dimensions such as the Nether of Minecraft. To find out how very small Darkfalls world is I had to use a different calculator and I think it giggled after. Minecrafts world is well over 18 billion times the size of Darkfall's island.
It has free for all PVP with full loot. You can PVP at will, or team up with others and do massive battles.
Minecraft also includes a permadeath option. If you die you not only drop all your items, but cannot respawn. More Hardcore than Darkfall Unholy Wars, if you want that!
Crafting is a much more neccesary and integral part of the game. If you craft items or harvest raw materials, Minecraft is by far the better choice.
Darkfall UW has big sieges you say? Minecraft also allows construction of such things as cannons, ladders to climb castle walls, it has mounts, and offers a massive scale in terms of number of players fighting as well.
Minecraft has massive advantages when it comes to construction. Not only can you choose where to build your structure, but you can also alter the terrain to build it. You can build all sorts of structures from a cottage, to a castle, to a fortified keep with massive kingdom surrounding it.
Minecraft includes numerous other features from many kinds of crop growing and harvesting, to animal farming, to building traps for players or NPCs, or crafting and constructing quicker transportation systems, to advanced circuitry including automated music, Day/Night cycle with an effect on gameplay, weather, fishing, cooking, to making hidden passages, hunting monsters that can be very dangerous, as well as vanity and combat pets you can tame.
There is no tab targetting in Minecraft, and it has the further advantage over Darkfall UW of not needing any grinding to be effective in PVP.
Minecraft includes far more dungeons, underwater areas, and places to explore than Darkfall UW as well. It is even possible to build your keep underwater, in alternate dimensions such as the Nether, or in the sky. When you're looking down at the clouds from your castle in Minecraft, you'll realize the sky is not even the limit!
Minecraft also includes enchanting weapons and armor, as well as brewing potions and poison bottles to throw.
Minecraft is released on both PC and Mac, and has editions available on iOS, Android, and Xbox 360.
Minecraft also does not require a monthly fee. It is buy to play, and playing online with others is included.
Nearly 9,000,000 have purchased Minecraft on PC or Mac, which I believe is ever so slightly higher than the number of people who bought Darkfall (any edition) ever.
So if you are looking for a better indie sandbox FFA PVP full loot game than Darkfall Unholy Wars, Minecraft is out now.
If you're dead set on Darkfall Unholy Wars, that's fine too, let's hope they announce when they plan to try releasing the game soon
