Fuck, this game can get really annoying, especially when facing someone like Lau. I have to 'work' for my damage and all Lau needs to do, is P P P K or whatever to do 40% damage on me, even when I only let my guard down briefly. What's even worse is that he can kick you out of a half-fenced arena as well with that same combo, and that's just bullshit. If I do an Offensive / Defensive Movement, said combo just so happens to keep tracking me.
What even more annoying, is something I discovered with Lei-Fei. If he's on the ground and you anticipate him doing a low sweep, HIS low sweep will get a higher priority than Goh's up + punch, almost every single time. VERY annoying when you only need to do that much damage to finish him off, and it's not like Lei-Fei doesn't have a versatile move set either (unlike Goh).
No idea if Goh has any damaging counters (the one that cancels punches does absolutely nothing at first glance), because I could sure it. And I'm also kind of annoyed how easy it is for some character to combo you off the ground, even if a punch visibly doesn't hit you.
Oh, and another thing: ranking up online is bullshit too. I fight a 4th dan, I barely beat him and I only get a fraction of experience, while a 1st dan that beat me received
25% exp from my bar AND ranked up. If I were to do the same, I would never get the same amount or anywhere near it...

The demo was shit, like so many other demo's, so you'd be better off renting it, since the retail version DOES have an in-depth tutorial so you can learn to do something else other than button mashing. VF5 is my first Virtua Fighter and I'm doing just fine thanks the Dojo Mode (ignore the above rant

).
