Clearly, when they're done right and attached to a great game, motion controls can be accepted by the "core".

Red steel 2 is an amazing prove that NO

Eventually, but not for some time I reckon.

Infamous 2, Heavy Rain, Bioshock infinite, resistance 3, killzone 3, CSGO, mlb the show, portal 2, and LBP 2 are all core games where motion controls (PS Move) are a great add on to the experience. The wii also proves how motion controls can be accepted by core gamers.

I'm part of the vast minority that enjoyed the infamous "waggle". I loved it far more than full motion controls that were often intrusive or buttons only.

That includes both Galaxy games, Zelda TP, DKCR, NSMBW, among others.

I really liked No More Heroes and I made sure to buy a Move and will be playing Sorcery and Killzone 3 with the gun attachment if it works well. With the move, there are just some games that don't work well with it in my opinion, like InFamous 2. I thought it was awful using the move as the missing analog stick in the navigator/move set up. Like Media Molecule said recently, no one has made anything really good for the move because they are trying to recreate what the Wii did (for the most part motion controls that haven't appealed to core gamers) instead of using the Move's strength as a precision 3D spacial tool.

The main thing holding back the Move are developers not willing to make stuff with it truly in mind, second is the PS Eye. The new PS Eye will really improve the Move and I hope that will inspire some devs to do more stuff with it.

Media Molecule sounds like they are doing something really awesome with their sculpting game. That "rock band" they showed off was them controlling those characters themselves. Characters they made with the Move and programmed their arms to map 1:1 with theirs, created instruments, and actually played the instruments. That is something any gamer could create with the tool they are working with. Essentially its a 3D game creator, and that is f'n awesome.

I disagree with u for infamous the move, for me, made it much easier to play the game since the aiming was far more accurate and faster vs the ds3 controller. The layout for using the move was almost the same as the ds3 controller except the orb was the right analog stick.

I'm a core gamer and my favourite controller is the Wiimote.
Deal with it.

Core games with motion controls appeal to core gamers. Naturally, motion controls were more appealing on Wii for such games where it was the primary input as opposed to other systems where it was an after thought.

Maybe you had a better set up than I did and I agree the accuracy was nice, but it was the screen movement that destroyed it for me. I find moving the camera far more important than straight accuracy. The control set up also require you to maintain a fairly unnatural stance in order to control the movements properly. The move should have had an analog stick on it and allowed for dual analog stick motion control gaming.

In the end I couldn't turn left to right or look behind me in a suitable, accurate, and quick fashion to actuallly play the game well.
