worst thing of street fighter games is the ****ing charge of 2 sec (example characters as guile - balrog - vega - M. Bison) the cpu never make a charge, it launches 2 sonic boom in less of that 2 sec, that's a shame. but personally I love it, Akuma - Gouki rulz
Well, only the cpu can do this, and the cpu has been known to do this to high degrees of frustration. Back in SF2:WW, this was the most overpowered M. Bison ever, he had no charge knee presses that could keep you in block stun, and if it connected once, he could do it instantly and make you dizzy, not to mention you lost more than half your life as well, and of course characters like Guile could shoot sonicbooms and keep up a fireball fight with you even though your characters like Ryu, Ken or Sagat, so yep, the cpu's are known to not have the no charge handicaps.
However, the whole concept of the 2 second charge is very key as well, I mean, just imagine if Guile didn't need to have 2 second charges for his sonicboom or flash kick...the guy would've been Top Tier in everysingle SF2 version, because he has almost instant recovery from his sonic booms, and his flash kick, although not as effective as his sb would've been incredibly powerful w/o 2 second charges.
About the system direction 3S tournament, I highly doubt there has been any, and if there is, it's within a small group of a fighting game community or just among friends. Because by altering the game, your changing how the game is played drastically, which is why you don't see any tournaments of such kind. I mean, take for example in the extra options menu, your allowed to add more stocks and make bar's larger, this alone can make characters who weren't as strong, even stronger.
Say someone like Ryu, he's already a solid character, and is ranked within middle tier. However if you allow the ability to have 1 more extra stock, this can make Ryu a powerhouse, because now he will have 2-Stock ShinShoryuken, or 2-Stock Denjin...and anyone can guess just how much of an improvement this can be, because Shinshoryuken wasn't that great because you only had 1 long stock, so you had almost 0 ex-options, however with 2 stocks, you can basically use ex, yet be capable of landing a Shinsho in the match or what about having to up against a Ryu with 2 fully stocked Shinsho's...that's just crazy, and with the return of 2 stocks, this makes 2-stock Denjin Ryu almost equivelant to his 2I counterpart, which is extremely powerful, 2 fully stocked denjin connected ='s 1 free round basically.
My friends and I where messing around with the extra options and the sys. directions, and we happened to turn off parry for one session. LOL, this made Denjin-Ryu Top Tier, every knock down(Only a few characters can get away from a knock down Denjin setup..Yang being one if he has a full meter and is using SAII), every buffered Hadouken was guaranteed Stun Damage, this was just sick and funny, but yeah, it seems like almost pratically everything we did, my Ryu seemed to only gain advantages, Gouki is also extremely powerful with no parry, because his aerial fireball becomes a very dominant and powerful tool, and since it makes Gouki's rushdown game even more powerful not to mention more difficult to counter.
Having an extra stock is also pretty crazy, because a character like Makoto becomes even better as well(not like she needed it, really) because her SAI which was only one stock, is now 2 stocks, allowing her ex-options and yet the ability to utilize her powerful SAI in the process, of course as stated above, Ryu benefits greatly from an extra stock.
All Super's Allowed was fun too because now Chunli has her SAI as an AA, so this can be a good tool up against Yun and even Yang, since one of her problems with fighting Yun was not having a proper AA for his dive kicks. Gouki has advantages from this as well, since he of course has the largest list of SA's and having them all obviously doesn't lower his gameplay but only improves it, and Ryu is a no brainer, Shinku, Shinsho, Denjin all in one, this is just too good.
I noticed things like no gaining meter with wiffed attacks can lower advantages for some characters like Yun who can build alot of meter from wiffed attacks, and if you increase the bar, Genei-Jin isn't as spammable as before, and although the bar is longer Genei-Jin only last slightly longer not enough for it to benefit from the longer meter and of course the no gaining meter from wiffed attacks makes it more difficult.
I honestly thought a character like Chunli "would" lose some potential from the no gaining meter from wiffed attacks, yet even though this tones her down from gaining meter by spamming regular attacks, she is still strong.
But yeah, like I said, this is what system direction can do, it greatly alters the game, reasons why you don't see any tournaments held for it. Still in my opinion, it's fun to mess around with it once in a while and experiment.
