How much does a credit set you back on average?
Where I used to live it was 1RMB for 1 credit. 1RMB is about $00.14USD, or .12 pound sterling. So to play any candy cab game it was just 1 credit. Some of the shooters, like Let's Go Safari, House of the Dead 4, the Taito Elevator Action lightgun game were like 2 credits or more. There was an Outrun 2 cab with four cars and a camera to get your face on the cabinet and the cars moved and shit, that was 4 credits.
This arcade I went to tonight was a bit more expensive, about 5 credits for 10RMB. I only played Outrun 2 and that was 5 credits. Everything's more expensive in the capital, that's true all over the world.
edit: cab on the right was SFIV, guess I took a pic (who the fuck takes pics in an arcade anyway? can you guys imagine how fucking lame I felt doing that, all the while thinking 'whoa can't wait to share this with my ng.com bros'? fucking gay) while stage was loading or whatever
