Amazing deal
Let me first say that the pump series is a fantastic series. Its much more to my liking than that of ddr.
The pump series offers a great challegene than DDR and a more forward song selection.
Each pump game comes with 3 music sections before zero and 4 sections after zero. Banya(which is mostly classical remakes) Kpop(korean pop), Pop(which can be any music as long as its not korean) and Nightmare which is just a collection of songs from each section with really hard note charts.
Pump games are drastically harder than DDR.
The interface is a little combersume to get use to in arcades because there are no buttons or menus. Everything is done like old ddr where you enter pad combinations to turn of modifers.
This is a really great deal. Only odd thing is this type of game really has no value being on psp.
