Jason I'm not gonna learn anything from watching combo videos until I actually play with the game. Combo videos are the least helpful thing to look at before knowing anything about a game, now that I think about it. Combos are not very interesting to me especially I know how hard they are and what the player had to do in order to land the first hit on the opponent.
First things I need to know are the basic mechanics like how many buttons are used, names of buttons/inputs, the combo SYSTEM (like how combos work), and guard crushing, tag system, meter, and comeback mechanics -- how the game works on a basic level.
Then I need to see movelists... I need to see every character and every move in the game. [Aside: I learned VF5 very quickly from going through movelists, understanding common "rules" governing attacks. Lows are -frames on hit, mid circulars are -14 punishable, fastest mids and combo starting highs are i14. This was a HUGE problem when I was learning Tekken, with 40 long movelists to go through which were full of useless moves and long strings that you have to know the sequence of or else you can abused to hell. The move properties felt pretty random too, but it being pretty similar to SCIV and VF in a lot ways helped. I eventually gave up on learning everything in Tekken since I barely like that game anyway] I gotta know what everyone can do, and its better if I choose my main or team after seeing all the characters.
THEN I watch match videos, but only ones with my character and team. Here I'm trying to learn how my character is played and how that differs based on the matchup. After a few match videos I'll look at special tricks the character has and frame data on community sites and analyze the choices players make. If I still haven't touched the game at this point, then I learn combos. Even then it's really better to wait... it's hard to remember them until you are familiar with the moves and mechanics.
yeah, sorry, my posts are too long. I'm not free on thursday but I'm down for non-smash events
