I must admit, the 3d effect is growing on me. I see it's value, but have to turn it off at points when I'm moving around too much.
I still hate that the background characters in SSFIV don't move. The game would have been better without those background characters, the actual player character models look really good and it plays really well.
I do wish there was a good adventure or platformer game, not a remake, but an original title. I never played cave story so I'll pick up that remake. Other than that, I wish I had something to look forward to.
As far as issues, I had my Nintendo 3DS freeze while navigating the home menu, but it hasn't frozen in game. Doubt it will have the hinge cracking issue, it's really well built. It feels really good, it feels metalicy. It doesn't feel like a piece of plastic like the DS.
Other than the price, it was really a great buy. It reminded me of turning on a new nintendo system as a kid, the only thing missing was a packed in mario game.
