Miles is onto something with that "small puzzle" idea, but I'd take it one step further and never actually play. I'd spend the whole night just pulling out the truly awful covers to groan at, like that weird photoshop on the original Mega Man box. My friends would leave and I'd still be there sorting.

Learned that lesson the hard way after some cheap patch cables I bought shorted out a whole rack. The extra few bucks for decent ones saved me so much trouble later.

Could be weeks, could be years. Total crapshoot.
