[…]it has a few issues. This version of ME3 seems a lot less visually stable than, say, the Xbox 360 version -- the frame rate is choppier, the animation seems rougher. The audio suffers, too; while the music and sound effects have come over fine, all the dialogue has a hollow, echoing quality to it. The GamePad's analog sticks aren't as comfortable as the 360's, and the placement of the face buttons relative to the right stick made me continually miss the melee and reload buttons.
[…]Wii U Controller Pro rectifies some of these control issues -- it's pretty much a 360 controller, and it works great. […]you lose the GamePad features if you use the Pro, and the GamePad is actually used pretty well here. By default, it serves as a quick skill-select menu or live map display (yes, just like a DS game), and […] There was some actual thought put into this port, which is always nice to see.
The real advantage to the GamePad, however, is the fact that the game looks much better on its smaller screen. […] the game plays noticeably smoother on the GamePad screen. The stiffness of the characters doesn't come across as readily, and the compactness of the visuals makes the environments seem far more beautiful and detailed.
[…]The game kicks off with a 20-minute digital comic that allows you to make key choices to shape the plot[…] the most interesting moments in ME3 came as outcomes of smaller choices that aren't included in this prologue. So while you'll still shape the outcome of, say, Tali's major plot arc, you'll never know the pleasure of helping Conrad Verner find true happiness.
