I haven't had much trouble with the online, except for the fact that most of the attack sound effects just drop out during most of the game, and those are pretty integral. I haven't completed a match where I felt I was left open to attacks when I shouldn't have been or anything like that. The only other issue I noticed was strange: I was playing a guy who was using Bob, yet Bob's super art, in this particular match at least, seemed to do no damage to me whatsoever. It was either that or the damage just wasn't reflected by my health gauge.
But, aside from that, the point remains that this game is most fun when you have a friend playing with you in the same room. In fact, that's true about every fighting game probably, which is why arcades were awesome when they still existed where I live.
I know it's just a number, but I don't think bad online play and the weird implementation of the gem system is enough to bring this down a full two stars. First of all, I'm fairly sure that the online bugs can be patched. If for some reason they can't, then okay, it doesn't deserve more than 3 stars...but again I prefer to play locally with friends who grew up playing SF and Tekken in the arcades like I did. I loooove Capcom, but strangely enough the only fighting game I play online regularly is Soul Calibur V.
And as far as the gems go, I honestly didn't see them ever being crucial in winning a match, whether it was me or who I was fighting. But still, whenever I'd pick a new character, realizing that I hadn't configured his/her gems how I wanted, I definitely felt the need to go back and do so as soon as possible, just because the fucking one empty gem slot was frustrating to even look at. By now I'm sure people have figured out gem combinations that totally work for them and help them kick ass all over the place, but I haven't. That being said, I do think it makes more sense to have these gems on a per character basis, but they could have easily just had a few sets of default gems that could be applied to any character in the selection screen. But again, this could be easy just to patch in too, couldn't it? Hopefully they're not taking notes and saving all the fixes for a "Super" or "Ultimate" SFvTK.
But I'm not criticizing Jeff's review, just giving another perspective. This seems to be a polarizing game. I'm actually still kinda stunned they even pulled it off. But, I love it, you may hate it...it has flaws as all games do. Hopefully online issues will be fixed, if not, the core game is enough for me...but I understand that that's not the case with everyone.
Also, I got the special edition just by pre-ordering the game, maybe the special edition is only more expensive if you hadn't pre-ordered it, I dunno. Yeah, I got a ton of extra gems, but the real prize was the awesome arcade cabinet piggy bank. All my change in one place, fuck yeah! And in a tiny arcade machine, no less. I think they're trying to say something...arcades are dead, so now your change belongs in fake arcade machines.
