Nice to see more fighter support on Vita!
Nope, now that 3DS isn't that weak tech wise so they're trying to follow the same game console route of the PSP and Vita when possible. 3DS has a lot ports, remakes or new titles of home console games IPs.
If they don't do it more (or did it more in the past) is because of lack of horsepower or proper controls for some genres. It isn't something related to design. This is why most of this games in 3DS that are from last gen or older, or sometimes have to make a new game instead of just to port.
But hey, when they announce Ocarina, Metal Gear 3, Pilotwings, Resident Evil, Street Fighter IV, Dead or Alive or Monster Hunter (just to name some few) in 3DS nobody says OH NO console games! In this case people who says that this happens in Vita and it's a bad thing doesn't whine.
There are a lot of people like me who wants to play certain current gen games in portables and are happy with it. If there are others who prefer to do the same but with a N64 game instead, and with games of really miked old IPs. It's their choice. As valid as ours.
Gravity Rush, Sound Shapes, Escape Plan, Dokuro, Army Corps of Hell, Mutant Blob Attacks, Tearaway, Orgarythm, Unit 13, Souls Sacrifice, Sumioni or Dragon's Crown and many others are bringing a number of new IPs tailored for the portable. Let's say that it isn't weak regarding to this when compared to 3DS.
