I bought Ghosts for Wii U because of Wiimote and the tablet controller enhanced local multiplayer, and they work absolutely amazingly superbly!!! I find this version to be easily the best version for me, and I also find that the 70€ was not enough for showing my gratitude for getting this game in this current anti Nintendo hegemony. Thank you very, very much!!! I at least have one really good FPS for Wiimote.
But! The tablet controller needs gyro aiming for fluidity, accuracy, immediacy, and being able to compete with Wiimote without auto aim. I will pay another 70€ for buying it for a present for some one if this happens! The gyro aiming with a big screen in you hands, aided with regular controllers, is very close to Wiimote in accuracy, if not just as accurate, and perhaps even better in immersion. It's practically, well, in fact, also actually virtual reality, just with smaller screen. Just try it, it's like magic, only real.
Also, take away the auto aim from Wii U version altogether. We finally have a console, that doesn't need computer to make gameplay decisions, so please support it accordingly.
In Wii U version players would also be able to control leaning for him/her selves with nunchuck. It worked very well in Wii version of Medal of Honor. Please update it asap. I don't like automation in games; it's anti gaming.
Here's a BONUS TIP for next game:
Use the tablet controller for commanding your squad in an RTS fashion!
