You know I have been playing brawl with chillin the last two weeks. Basicly working sleeping and playing brawl. And AS OF NOW there are no real advanced tech's the only useful one I learned how to do is glide tossing. But yuna you cant say that the game is limited. When you watch videos of melee when it first came out it was the same thing. just give it some time man.
That was 7+ years ago.
The Smash scene was tiny, miniscule compared to today. They were also fresh from SSB64, which didn't really have that many advanced techs. Now, 7 years later, the community is huge. And we're vetted and much more technical.
What was the first thing we did when we got the game? Start looking for advanced techs. 4 weeks later and what have we found besides what was to be found that first week despite intensive exploration? Pretty much nothing. We know what to look for and the ways to look for them.
In a game where most ATs were removed and all the new techs are intuitive and really easy to do, do you really think Sakurai inserted a slew of ATs that are so hard to find we haven't found them yet? No, they most probably do not exist.
And even if they do, the game engine itself is extremely limited. Falling speed, attack speed, comboing, Stale Moving, increased floatiness, increased DI, no lag-canceling, the new physics engine, less shield- and hitstun and much, much more makes gameplay very limited!
Even if we found a slew of ATs, they'd have to literally be gamebreaking. ATs in Melee did not break the game. They did not go against the physics engine or glitch it in such a way the game was played completely different. They just enhanced the game and gave us more options.
But in Brawl, in order for us to get enough freedom to come even close to what Melee or any other competitive fighting game is/was/will be, the ATs would have to work against the way the game is programmed so much we'd be playing a completely different game than without it!
