Hi everyone here, my TV is 3D-compatible and I enjoyed playing AC3 in 3D (I discovered I could do it yesterday).
So this is basically a topic made to discuss your feelings about the 3D playing experience.
Edit: perhaps, to start the discussion, I have to say the immersion feeling is extremely enhanced in 3D mode.
I've also played in 3D, though I prefer to keep online in 2D.
The 3D is awesome. There are very few things in your face, but there are many linear elements that help in creating a sense of depth beyond the screen.
The perspective I used was 0 (zero)... good separation of far images and not a big separation of the image of the main character... for AC3. Zero is bad for stuff in your face, but since the game had little of it, I went with zero for the far depth.
When there it was snowing, I used +1, because it helped with the snow in your face, though the far depth suffered a little.
