I used the same 'form' as you to add my own two cents. Hope you don't mind C:
First impression
I was bouncing in excitement when I finished the download of the game. I was really worried that it wouldn't work, since a lot of people were having OGRE exceptions. Fortunately for me, everything went flawlessly. I heard the familiar music from IT and squee'd. It was so pretty! I tried multiplayer of course, first, then saw the servers weren't working. I had been hoping they'd have them up when the game was actually released, and was disappointed. (I later found everything out).
Character editor
I had seen this before on the livestreams, but didn't know it looked so good! I was really excited when the game was first announces about being to change proportions. That got me really excited. I loved all the tail/mane/ear options, despite the few glitches. It was hard to decide which ones my main characters should have!
Map maker
The only reason I knew how to do this was because I was constantly on Tigg and Delay's streams, and they taught me how to work it. I admit that it was probably confusing for someone who had no clue, but it was superb in general. SO much easier than IT's. I have 2 WIP maps so far, and they're looking great.
Sky maker
I found this really easy. Figured it out in a matter of seconds. Don't understand what is so hard about it xD
Object maker
Easy. I was sad that there were very few objects, though, compared to the resources Tigg & Delay had in the streams. Then again, they ARE staff. I did finally figure out how to import the palm tree and waterfall, though.
Actions
I got on Multiplayer for all of 5 minutes and did get to test them out. They are flawless, and very realistic. Love that the buttswing/headbang are back from IT! The only one I don't like is the laying on back one. The paws/legs look so.. stiff. Like they're being forced up, or on a string or something. On IT they looked a bit more relaxed.
Multiplayer
For the 5 minutes I got on, it was great, but so laggy. There were, though, hundreds of people in one map, so it was expected. The game crashed before I got to go to another mao, though. I'm sure they look great.
