Hi,
Ooh, fighters, that's a tough one
but good luck. My advice would be start small, keep it simple, and go one step at a time.
So, maybe next you need to learn about DBP animation basics and collision. Don't worry yet about input systems or cameras, models, thats the easy stuff!
Just get two models, with basic collision (e.g. stick boxes on their hands, and have 1 boundary box per player) and get one to play a punch animation, and if it connects in the other plays bounding box, get him other to respond with a "been hit" animation.
I would say a wresting game is the hardest fighter, you may want to start with boxing, which has no grabbles, throws etc. Wolf started a good boxing game a while back (remake of Punch Out I think?), so you may want to look at that.
Hope it helps,
Cheers.
