:/ Nintendo, smh.
I get Nintendo is always trying new things, but this isn't an interesting new thing, it's just a poor business decision that will earn them alot of flak when PC gamers get only "half" of a game.
I should also say that I doubt the multiplayer on a WiiU FPS/TPS will be good enough for a PC gamer to make them even bother with it. The only interest PC gamers would have in the game would be the story, if it all compelling.
Nintendo could easily make a lot of money if they weren't being such stuck-ups with their products and brands.
I don't think you understand the PC gaming market or Nintendo.
First of all, the loud vocal group of PC gamers will complain regardless. It has a console version. That means it's either going to be a bad console port or a watered down-for-consoles game.
Second, PC gamers care about the story? Last I checked, the top three played PC games were all multiplayer. And even then, games that do have storyline often aren't really cared about anyway. I don't play Skyrim or Fallout for its storyline (don't get me wrong, it was interesting, but I'm pretty sure that wasn't the selling point for most PC gamers who bought it). And the games that I have clocked more than 40 hours in (my average time to complete an RPG) are sandbox/open world style games or games that I've modded to hell and back.
And besides, the PC version is free. There's really no risk in getting it.
