Now that brings memories. Never did it myself either, but back when credits were fifty cents or one peso, there were HUGE arcades in Mexico, with all the best games. Many people told me that would work on some machines, but many others had tokens. And each token was one, then two pesos, I think. Those were the days. Nowadays, there aren't even Tokens anymore, you have to pay for this phone-card like thing, or a key-like thing, and have credits transferred to it. And games are EXPENSIVE. There was a Free Play place in Guadalajara, around 1994-97. You paid 20 pesos (which started up being 8 dollars and then it was like 3 dollars and a half), and you could play anything all day. That one, too, has become one of the key-thing arcades now.
