completely and utterly(only watched a few vids) god damned pointless. just once i wish they'd do some world championships for dancing crap games and have them program a new track in, so they all look at each other and go "wtf, i haven't spent 2 years memorising the crap outta this, wtf am i gonna do now".
when it comes to more basic games, like a top down scroller where the ships spawn identical places every single time, or dance things where you learn the notes, non of its skill its just an ungodly obsession of time memorising. that is a skill itself, but i personally don't think its one iota of gaming skill at all.
a level of CS, while say on office generally people go the same way most times, they can be anywhere, pop up anywhere, you can play against different numbers of people every time up against different weapons which all change tactics. you can't simply memorise it, as you're playing against someone basically. thats where streetfighter to a point has slightly more credibility than dance dance and other crap. but the combo's are still all about memorising. he also knew the timing to do all the blocks because he would have memorised the timing of chun li's kicks by playing it for ages.
i don't know, i guess i could, so many people play to a point and force themselves to learn say, if theres a whole in the wall people snipe from, people learn to get to a exact point, pop out and the bullet will hit that whole in the wall. i never bother learning that exact, i just play on instinct. memorising maps to that level, or vs computer games completely takes all the fun out IMHO. which is fine, but again i think its not gaming skill whatsoever, its simply, i can move my feet fast skill, or i can memorise which button to press in order.
but thats just me.
