The totally reliable Kotaku claims that a special version of the PSN game Gomibako (Trash Panic) has been released in Japan. This one costs only 100 yen (about US$1) to “buy”… except that this isn’t the price for the game, it’s the price for three credits! Once you’ve used them up you can buy more, at the same price of 100 yen for 3 credits.
Sounds weird but I think pay-per-play is not perhaps a terrible idea – the problem here is that (as usual) the price is far too high. I don’t know the regular price for Gomibako but you can get full games on PSN for $5-10, not to mention those newfangled $1 iPhone games. This kind of micropayment has to get a lot more micro to gain any traction.
