Ok, bry gave me this topic, i just gotta respond to this...
The reason I like/play fighting games is because they are simply the most versatile games ever. Especially games like KOF. in KOF, people can play so many different ways, you have your throws, standard attacks, special attacks, supers, and you have all kinds of evasive and defensive manuevers, like rolls, throw escapes, etc.
a lot of fighting games just have infinite depth. I doubt that very many people, less than 25% of the people who buy fighting games actually try out the system, actually read about it and learn to use it, or use combos. And strategies are infinite. The way you play makes it more interesting; ultimately, fighters are a complex mind game.
and competition! another huge reason to play fighting games. nothing feels better to win a really close fight, or to totally own someone at the arcade. i can see why people get "bored" of fighitng games cause "you beat it, and that's it." it's all about Vs. mode, people. and hiking up the difficulty.
Not to mention characters are great, and there are always a good number to master. attacks and combos look damn cool, too.
And most of the time, fighting games are difficult. I don't know about the rest of you, but usually, that's a plus in my book.
but to summarize:
-Fun
-Depth
-Competition
-Difficulty
read some FAQs on the fighting games you have, i'm willing to bet anything you haven't explored them to their fullest.
