Well, I decided after little deliberation that since you can install the 2 alongside each other, I`d give it a try. After 10 mins I've established the following...
1) I have to run 800x600 with all detail turned down despite having a pretty decent computer.
2) One of my secure chests in my log cabin simply disappears in the KR client.
3) Moving around on a giant beetle is terrible (running sideways and cant really tell which way you`re pointing)
4) They`ve changed the movement system so if you aim yourself into a wall (like the bank) it tries to run around it regardless of what way the cursor points.
5) They should have just used UOAM as a template for a map system thats actually useful.
And the good bits...
1) Ooh its all pretty looking!
2) The macro system looks like it could be quite good
3) I love the drag n drop additions and the new backpack (but then, I do play WoW too so I'm used to that)
4) Hotbars!
All in all, I'll probably tinker about with it to see if I can make it into something that I can use, but otherwise...its 2D for me.
Thanks for the input guys n gals
