I always thought this was just me!
Nah, I think it's a widespread problem. I think it's because the supposed "hardcore" fighters are becoming slightly more mainstream (SF becoming mainstream "again" with SF4) so a lot of people who are used to typical 3D fighters (See: Just about
anything that Namco puts out) are just unable to do the combos efficiently at all.
My closest friend, who I can play fighting games for hours with, becomes a master at just about everything he plays (making it unfun to play against him sometimes, haha) and even he couldn't come to grips with the timing of SF4 combos.
Not being able to pull of the combos didn't stop the game from being a blast though, because it was still a heck of a lot of fun to play with a bud. I'd much rather put a game into my PS3 that has easily chainable combos though, such as Soul Calibur IV.
Anyway, my copy of BlazBlue has been halfway across the country since last Friday, awaiting review by customs. Should it.. Uh.. Normally take a
full week???
