Steps to making a fighting game?

Hi, I’m completely new to Unity and was wondering if someone could lay out the steps I would need to take to create a fighting game in Unity3d? I don’t expect for anyone to lay out scripts but more so the process of how I would go about getting started. I want to create a 2d fighting game reminiscent of street fighter 3rd strike, maybe that’s a bit too ambitious but I don’t expect it to be done for a few years and I’m hoping to learn things along the way while making it. So if anyone could offer advice on the steps I should take first, whether it be scripting or creating sprites and animating them, that would be great, anything to point me in the right direction. Any help would be appreciated

There’s a great guide from our resident fighting expert n0mad here: http://forum.unity3d.com/threads/19299-fighting-game-Kinetic-Damage

Thanks so much
