I have not played Epic Mickey 2 on any system but I can answer you regarding the other two
Batman Arkham City
I have played the game on my PS3 and it is really awesome game with great narrative, decent melee combat, and really exceptional unique batman gameplay which is best part of the game. Unlike a shooter where you go area to area with new baddies to shoot in the head, in Batman games in each new room you have a new situation where you have armed and unarmed goons and you must do as batman would. Often there are also hostages to save so it encourages being stealthy for that reason as well as it is easier if goons stay unaware of your actions. The great thing is that it isn't a puzzle with one proper answer but rather a wide set of tools at your disposal and open ended solutions. It is very satisfying.
The Wii U version which I have also played adds some interesting use of the Gamepad. I know already I like getting separate sound from the Gamepad in addition to the multi-channel sound from my speaker system because that adds immersion. Being able to tap on the screen to detonate explosive gel is also good and using touch to work with "pause" menu can be more intuitive. The "pause" menu via Gamepad while you ignore the top screen or using the top screen in pause menus is just a change and doesn't streamline the gameplay better. It takes a little getting used to looking up and looking down.
The Gamepad+ points aside, the Wii U version of the game doesn't look as good as the PS3 version of the game. It's equivalent most of the time, but sometimes the bloom lighting is too much and textures are worse than PS3. There is no loading added, framerate is solid, but saving at checkpoints can sometimes stutter the game for a second or so. Maybe there will be some patch that addresses some of that but not currently
Ninja Gaiden 3 - Razor's Edge
They completely fixed everything that was wrong with the X360 / PS3 version of the game. It looks great and plays better. The best thing in my view is that the challenging AI from past Ninja Gaidens is back. You now have multiple weapons and an upgrade path. Lastly, it allows you to easily switch difficulty up or down between Hero (Easy) & Normal difficulties so that you don't get stuck on certain difficulty spikes that occur such as boss fights.
They took out the crappy competitive online mode from X360 / PS3 version of the game and added co-op mode similar to what was there in Ninja Gaiden 2. It works great. The game also one of few Wii U launch games with SpotPass support.
Personally, I think it is the most stylistic Ninja Gaiden game to date and progression wise it is 2nd best. If you liked either 1st or 2nd game, this is for you. It's action gaming nirvana.
