/jp/ - Otaku Culture

I've been looking into playing iidx for awhile after ive played the shit out of sound voltex, but the amount of information concerning what controller to buy, the amount of versions there are, sync and lag issues, alongside this random and towel shit I know nothing about makes me a little anxious. Am I too late to hop into the scene? Can someone give me a run down explaining iidx in general to someone who knows nothing about it?
