Blugh, SSFIV was a bummer of an experience. Those lifeless ugly backgrounds with the cardboard cut out 'still' animals and people were just depressing.
Plus enabeling '3D' shot the game down to 30 frames per second. Which i find hilarious, considering Monkey Ball 3D imo is visually more pleasing than SSFIV and that's running at 60!...
And personally, I'm just not into online gaming....I find it to be lifeless, and far less enjoyable than actually playing against somebody like back in the good old NES/SNES days at your friends place or getting together at the arcade. 
SSFIV is hands down the worst 3DS game I've played of the....er...4?
Nintendog's was quite the snooz as well. Both games for the most part offered unimpressive 3D effects as wellzy'. Anyways, is Bit Trip 3D worth getting? I'm kind of leaning towards the Wii version, but part of me wants to just get both....then again, part of me doesn't even know if i wan't to get either. eek! 

lol
If this game didn't have any 3D effect to speak of i wouldn't bother with this one at all, it would feel completely pointless and a waste of time.....
