if your just starting out then your scope is to large. you are going to want to focus on learning to make smaller things first. learn to make a character blueprint for example. do a bunch of tutorials like this one to learn the basics of the engine and how to make basic games. if you dont know how to build the basic parts of your game then you cant make the whole of it. also fighting games are pretty advanced. they can be very complex to make given that so many things are based on proper / exact timing. the tutorial i linked will get you started in creating a player character, getting it to move, and animating it. that tutorial series is a set of videos that are only about 10 mins each and should only take you maybe a few hours to get though.
