A learning curve is only a problem if you are unwilling to learn. If you want to learn to do the crazy 30 hit combos, just sit down and do them. Its a game, not rocket science. The biggest key to a combo isn't mesmerizing the buttons you have to press, but understanding that you have to "feel" it as one motion. Once your brain recognizes that you hit and can go into it, you do. You have to be both confident that you can do it, and do it without thinking. Its like juggling. Once you start thinking about juggling, thats when you drop the balls. If your having trouble, have a friend (you know, a person that you know and like) try to help you out.
Also, DONT BE AFRAID TO LOSE! Its going to happen. I don't care if you Justin Wong, Umehara Daigo, or Ken Hoang; your going to lose at some point. Just try to see objectively what you did wrong and learn from your mistakes and try to get better. And if your not getting better, or your local competition is just miles ahead of you, ask for some help. Most reasonable people that have played fighters for a while (2+ years) will help you understand the game better.
But anyway, the real problem is that most people are scared of failure, and don't understand subjective development. Thats why there are rpgs are so successful now, they want the game to make them better over time, then to actually become a better player. That why I like fighting game, they don't care how long you play, what level you are, or how much gold you earned. If you are a better player, you will win (matchups and adaptability non-withstanding). You have to understand your skill level with a certain character (scrub to Pringles), your feel for match ups, and your ability to adapt to your opponents without the game giving you any details about your play experience. You have to know yourself and your opponnent. Weather you are a rush down, turtle, gimmick or whatever. You have to understand how to make the game adapt to your play style.
The person writing this article doesn't understand why people still play fighting games after so many years, or what makes fighting games fun. Its about competition, community, and understanding yourself. Sure its kinda a niche game stlye but its better then playing a game for 3 months just to get fucked up by some scrub just because he has better gear then you. And to play a subscription fee on top of it.
