I think Capcom should continue to make well animated sprites and backgrounds (maybe even more accurate sprite animations than those included in SF3). There should also be nice sharp 2D Backgrounds with Lense flare effect and whatnot. I only say this because people these days are spoiled by graphics, and they immediately asume that 3D will always be better than 2D. This new generation of fighters dont know anything.
When I think of 3rd Strike however. As far as further gameplay improvement goes. I think Third Strike pretty much makes you hit a wall… The fighting system is so perfect… that I cant really imagine going forward with Street Fighter 4. The parry system is a must right now, and not to mention they actually include Super Cancels as a basic part of the game.
I know Capcom probably has a big ego… But they should just go ahead and pull a shameless act. Its done SNK a favor (boo hoo, they stold Ryu, made him look like ken and named him Ryo - But whos complaining?). I think Capcom should just cut this little friendly rivalry with SNK and get down to business.
Right now the KOF series is way more progressive than SF. And thats because SNK continues to experiment and change something about the fighting system every year, even if its a minor change their still putting something out.
Simply put: Street Fighter 4 should have Small jumps (Not UOH), Dashing and Running (Its possible to have both, look at Neogeo Battle Coliseum), LP+LK Rolling, Each character in SF4 (old or new) should have a total of 6-8 Special moves 1 new Super move would also be nice. And yes, it would be nice if you stold the idea of what a Dream Cancel is (Cancelling Special Moves into Super Moves). And next time make sure Yang’s Seiei Enbu is as good as Yun’s.
Simply put, do what ever it takes for 2D Fighters to stand out once again.
And aside from everything I said. A Street Fighter 4 that plays exactly like 3rd Strike isn’t necessarily a bad idea. If SF4 played exactly like 3rd Strike. The only thing that the game will need are the following:
New and Old Casts (I’d like to see Cammy again, with a new set of moves, and cloth, and fighting stance, an older looking Sakura and Karin with both of them having mastered their fighting style - Sakura basically becoming that character that just so happens to hold a good amount of traits of both Ryu and Ken). Karin learning much more deadly moves (similar to that of Geese).
Sagat, Balrog and Vega (claw) returning to the fighting scene with new cloth/fighting styles perhaps? Urien fighting in his tux would be nice rolls eyes.
It’d also be nice to have a better hip-hop sound track in the game than that of 3rd Strike. Many fanboys would rather listen to J-Rock/J-Pop soundtracks but its a fact that SF was ment for hip-hop beats.
EDIT: The one thing that can change the way someone plays the game is basically adding new characters as well. People will have to think twice, especially if those old/new characters have a unique set of moves.
