I am searching a nice singleplayer FPS or TPS game for my Wii U. However I prefer IR aiming (with wiimote) or Motion aiming (Crossbow-Aiming in ZombiU was cool). It also should have a good singleplayer, cause I usually don't play multiplayer (my internet is too weak). Can you recommend me some games?

Black Ops 2 but i guess it is more multiplayer focused. Not a WiiU game but Metroid Prime Trilogy if you haven't played it and can get a copy.

This, plus Goldeneye 007 is good as well if you dn't already have it, and COD Ghosts is coming to Wii U soon and will support the Wiimote.

Ive not played it , but does 007 Legends use Wiimote/nunchuck controls? I think its by Activision, and from the videos ive seen it has a similar graphical style to Goldeneye.

call of duty blackops 2 or just wait for ghost both of them support IR aiming

So only COD or Wii Games? Sounds sad ...
