Where do I begin? Delay on strings, the triangle system and understanding when to hold, when not to. I'm a noob so I can't tell you everything, but I will say that I've played every fighting game there is and this one is the most difficult to win at consistently.
I think a lot of people try the game and they see and feel that its a lot different than what they're used to, they don't get it and go, "This game is dumb, its just boobs and half naked chicks". What I'm trying to say is people are lazy and just use that as an excuse not to have to pick up something new.
It's more yomi-intensive and less execution-intensive than other fighters. Think of it more as a high-speed strategy game, and you'll begin to appreciate it's complexity.
I think people just find DOA newb because they don't really understand the game. The punish system is bizarre in comparison to other fighters, and DOA is more just knowing your opponent & character as opposed to just playing the game. If you don't know hot to punish in other fighters it's no big, however if you don't punish in DOA they can just keep going which makes the game look spammy.
At a VERY basic level, DOA requires you to understand a move set. But it goes a lot farther than this. I can give examples about strikes in this game, and how effective they actually "can be", like in SSF4 for example. But that's actually an entirely different subject, not totally relevant here.
Exactly what you guys just said. DOA is unlike any other fighting game. Even other 3D fighting games. I'm a Street Fighter player to begin with so this game presents a completely different challenge to really learn to play.
Execution isn't really a problem, but the games' systems and mind game is something brand new to me. Easy to pick up, terribly difficult to be good at.
I think the issue is that a lot of people mistake high execution as meaning more complex and deep. DOA has just as much depth as any other 3D fighter, it just needs to be explored more. Especially when you factor in SE's into the stun game, you see how deep DOA5U really is.
What I'm trying to say is I'm not trying make DoA sound like a crappy game >.> But Bloods comment made it sound as if DoA is the only fighter that involves critical thinking/yomi. It's his opinion, but there are other fighters with broader match up's and yomi.
