That crap is confusing. I could swear Tekken (and Smash for that matter) is based on giving offline extra input delay to help with online matches. Yet his first explanation talks about how that is a problem.
With Tekken it always felt like the input delay gets to be too much too quickly. It's smooth, but a lot of input delay.
Nowadays you almost have to. KOF XIII was the last game I remember to not do this and it's pretty much unplayable (at least to offline standards). The problem I have with most games now is making the gameplay slower or more defensive (like SFIV) to offset this. I love playing crazy, balls to the wall offensive style at times, but online there's like a ceiling preventing a lot of what I want to do. So, to win most times I turn to either defensive, or methotical style. It works, but is boring after a while.
Personally I find myself playing older titles because it just doesn't feel as limited. I can play the same online and offline as I always do. I just wish the companies would produce more rather then getting the same titles on different systems. (98UM, 02UM)
