Ok, so before I do this writeup; I need to know a few things from you:
1) When you say you want to " i should say play for real", what do you mean by that? My default assumption is to learn to play the game in a skilled manner against human opponents. If this perception is off; let me know so I can direct you to the right info.
2) Which characters do you consider your "mains" (I get the impression Nightmare, but anyone else?) In case you are new to the concept, a main is a character which you are more well versed/more well educated; or in the case of a new player, a character which you want to become versed and educated in and are dedicated to doing so.
3) Are you familiar with the notations used on the site, i.e 3B, 66K, B6, 4(B), ect?
Please don't take my town as down-talking, I prefer to not make assumptions about your level of knowledge/lingo understanding. In this way I can get a better picture of where your at and advise you more accurately!
Awaiting your reply :)
