I liked M2 better.
Most noticeably awesome thing in M3 is the custom objects. M3 looks like you replaced objects in the editing stage, or added custom objects prior to duels, either of which is amazing.
What I dislike most about M3 is the frame capture that excludes the edges of the screen. It reminds me of swimming through water, or being drunk. Actually... http://youtu.be/7J2-ity2kIw
The video has frame skips, and looks like a lower resolution than M2(played at 720). Is this due to an extra layer or two of editing software?
P.S.: Your editing skills are far beyond what I could hope to accomplish, and I don't intend my comments to be seen as any more than casual observations.
