I've been a pretty big MH fanboy since getting the Tri Controller bundle close to launch. Since then, I've bought two PSPs, MHF, MHF2, 2x MHFU, MH Airou Village (Japanese), 2x MHP3rd (Japanese), and another Tri bundle. Most of these were on the cheap (except Airou and the first PSP), so I drew the line at importing a region-locked 3DS just to play MH3G. I did happen to be in Japan shortly after launch, though, and played the demo a few times in Bic Camera.
Well, i have been using the L button to lock on and it sometimes it feels better than even the right stick on the console version.
But the d-pad on the screen also feels right.
