No. Or not entirely.

There are two schools of thought when it comes to video game design who for a lack of proper name I shall refer to as realists and abstractionists.

The goal of the realist is to make everything as realistic as possible in order to immerse a player. Realistic graphics, realistic physics, and increasingly more realistic controls.

The goal of the abstractionist is to make everything as fantastical as possible in order to provide the best entertainment experience. Characters deflecting bullets with 100-pound swords, laser-firing robot dinosaurs, and increasingly more abstract controls.

To that end, the abstractionist wouldn't touch motion controls because it would make the more fantastical elements harder to implement, while the realist would embrace it because it's closer to the reality they're trying to portray.

Uhm....they do actually.

I enjoy playing some motion controlled games, as do many of my friends who are core gamers. They can be a lot of fun when you're playing with a group of people. This notion that core gamers can't possibly like motion controls is just absurd 

M+ and sixense are accurate enough I think, that given the right talent and resources, could be used for amazing games. Standard Wiimotes, not so much.

thats my point had those have been there from the jump i think it would have been received better all around, they werent and i think some people just said screw it by the time those came out and motion+ got atrocious support, worst than move or kinect

Maybe in quantity, but not in quality.

when only about four of those games are actually worth a damn and its been on the market since 09 that is nothing to be proud of.

Neither are Kinect and Move though. I'd still contend that neither device had a game in the league of Skyward Sword.

Killzone, Portal 2, Bioshock Infinite, Resistance, Infamous 2, thats of the top of my head, Really? The Move is getting support still and motion + hasnt for a while. Thats a fact. Skyward Sword is overrated probably the worst of the 3d Zeldas, i would place Portal 2 and Bioshock above it easily Kinect doesnt really do 'core' gaming so you got me there.

As has been pointed out above, motion controls will only be accepted by the core gamer when the input is responsive and accurate across the board. A few games have, for my mind, already achieved this but mostly in spite of the technology rather than because of it.

I haven't had  a chance to play Bioshock Infinite yet, (I really want to, I adore the first one) but I'd say Skyward Sword is easily better than Killzone 3, Resistance 3, Infamous 2, or Portal 2.
