Darkfall wont ever kill UO at all.
I was waiting for Darkfall to. In the past 3 years i tried OVER 20 different mmo's, including WoW, Darkfall and many others.
Well Darkfall, the idea was really great. A sandbox game wheres everything possible to do.
Those who followed the development of Darkfall online know it was a hard long way until this game came out, a small developer team made a nice job indeed.
BUT
1. They're saying Darkfall has 500-1000 different Skills.
Ok, they count EVERY single spell as an Skill. Means like you count Necromancy as 17 different Skills - like that you get fastly this amount of skills, just count once the crafting things together and you're almost there.
For me a small disappoitnment.
2. Housing - oh hell yes we heard it from MANY mmo's - Housing will come, we planed to include it on the release day but we didn't had the time.
We will improve asap.
Yeah yeah - Maybe they learned from Blizzard, which's trying since almost 5 years to include a housing system they told a long time ago.
3. NPC Mobs
There are certain spawnzones for mobs. Like goblins. The problem is, like 20 peoples are hacking on the 3 living goblins for one sec until they're gone. Then 20 peoples are waiting for respawn.
The AI isnt really so good as they promised. You may even block a few mobs with 2 players not hacking on the goblin then letting 1st player kill the goblin easy with his bow i.e.
Ok UO mobs arent very intelligent too

but DFo is almost 15 years younger (development counted) and there should be really a noticed difference.
4. Economy
Economy? WTF - If a player run economy should grow, there must be ways to get gold of course. 20 guys hacking on 3 goblins, each goblin drops approx 5 gold pieces. Even if the loot would be splitted fair - each player would get 0.75 gold per kill ;-) (i guess thats only in the starting area)
Well how the hell should peoples be able to run a player driven economy - no one has gold to buy items and all peoples are selling items ...
Wont work proper with this small mob-spawnzones they created.
5. The world
The graphics are not really bad. The game is running proper and smooth. But the whole world (at the point i played) didnt even had a single pet or something like a cow or anything else. Just an empty poor world.
6. PvP
Which PvP?
About the city hunting and owning there isn't really PvP, its just the point how good is a group organized or even more: how MANY peoples are in this group.
This game will end in a really big ganking mess. Small guilds wont ever have any chance to claim a small city or even try to attack it.
7. PvE
There isn't really a PvE content at all. I guess it's a PvP based game, but without a small PvE content the thing with the economy wont work at all.
Over all:
The try was nice. But Aventurine needs to fix and change many things until this game could be really playable. Im not really planing to jump into a ganking game.
At the moment it's just the matter how many peoples you bring together until you get what you want.
I quitted my account allready, maybe in one year i will have a look again, but i guess there will be a large problem with the missing time i dindt spent now for getting up the slowly raising skills.
