Who are these people that go around and vote in random polls?

Little do you know we all already have Steam Machines ;) 

Lol, total bullshit. That poll, as are most internet polls on gaming, is completely irrelevant to the real world. It's always just a competition between fanboys, in this case with Nintendo fans being the only ones that really cared about the poll (what did I say people? the worse the system does, the more vocal the fanboys become).

Also you're seriously using the point that there are no sims on the Wii U as a plus point? You do realize, that the fact that there has never been a racing sim on a Nintendo console means that there is no reason for a racing sim fan to own a Nintendo console exclusively, right? To release this game on the Wii U at all makes a very limited amount of sense and it would never have sold loads on the system, that's completely unrealistic.

I'm seriously running that point. People want all their games in one place. Wii U owners, unlike other console owners seem to love variety and the thriving indie scene shows that. The fact that the Wii U was the first officially announced console version(this game was going to be PC exclusive) holds a lot of ground for that version of the game. This game will fail on the other consoles and that's due to other racing games. This one offers nothing different on those platforms (i'm excluding PC from this). To release this game at the same time other racing games are coming on PS4 and One is just plain stupid. It would have been smarter to delay all versions and release with no competition to maximize profits on all platforms. 

Slightly Mad owe Nintendo & WiiU owners nothing, and we should be grateful an already stretched studio is bringing this game to their system with so much love. Most other 3rd party developers have shunned WiiU...

There'll be plenty of people working tirelessly to make this an amazing addition to the WiiU library. Surely one tongue in cheek statement isn't enough to make everybody turn their back on the game?

I think we Should be grateful this game's going to arrive with to much love and effort put into it, when other developers have snubbed the system entirely.

So people who like the variety of indie games and want all their games in one place will be happy with only a Wii U?

• Minecraft, flower, Fez, TowerFall Ascension, Resogun, Transistor, Don't Stave, Strider, Outlast, Valiant Hearts, Sound Shapes?
• Braid, Journey, Limbo, Peggle, Castle Crashers, Hotline Miami, Super Stardust, Brothers: A Tale of Two Sons, Luftrausers, Spelunky, Mutant Blob Attacks?
• Gone Home, Antichamber, Kentucky Route Zero, Papers Please, Stanleys Parable, Mark of the Ninja, FTL, Botanicula, Bastion, Gemini Rue, To the Moon?

All these marvels available on Wii U? Much better variety than on other platforms?

Not really.

The game was a  PC EXCLUSIVE  first, but ended up getting enough funds for PS3/X360 versions.   The WiiU version was announced later.

In the end, SM Studios cancelled the PS3/X360 versions because of PS4/Xbone announcements last year.

Nintendo owners, unlike others, love variety...? Really? Tell that to all those non Nintendo published Wii U games that failed.

And thriving indie scene? Yeah, sure that's nothing the other consoles have, I mean it's not like one of the Wii Us competitors is using indies as a huge selling point or is it?....

Seriously, you're making crap up here and are giving the Wii U fanbase some credit over the other fanbases that they really do not in the slightest deserve. Look at the Need for Speed game on the Wii U (literally the best game on that system to compare to Project Cars), that game sold horribly, without any competition to speak of, if I might add.

If the game fails, then it'll fail across the board and if it's a success then the Wii U will be the last place where that will be the case.

These are games you like, Stick it to the Man is on WIi U (I would argue this is the definitive version), I wouldn't even be surprised it most of these come to Wii U in the next year (aside from the ones that shouldn't be on this list, flower and Resogun). The fact that most of these are on PC sorta makes consoles moot here. For future reference, don't avoid games that are also on Wii U and do some research. The indie scene on Wii U has a ton of variety, nor am I saying people should stick with Wii U, what I am saying is that other consoles want triple A experiences all the time and indie gets ignored. A less powerful console allows for people to look at more than what first party there is (it also helps indie is heavily marketed on the eShop).
