Gamevil has been removing micro-transactions from its iPhone games
Cautious approach from the Korean publisher
Micro-transactions, or charging gamers for the option of buying extra virtual items or levelling up quicker - is going to be the big talking point with iPhone developers this autumn.
Games such as Flick Fishing and Enigmo have already experimented with the technology, which is part of the iPhone OS 3.0.
The likes of My Brute and Pocket God are going to support micro-transaction in their next updates, while ngmoco's online shooter Eliminate will use micro-transactions to effectively limit the amount of time you can play each day.
The companies that know most about micro-transactions, however, are Korean mobile publishers because all Korean mobile games use the system.
Over on PocketGamer.biz, Kyu C. Lee of Gamevil explains how the company is looking to use micro-transactions in its forthcoming games.
One significant point he mentions is it would be more flexible if the minimum price was less than the current minimum of 99c.
But what's really ironic is that to date Gamevil has been stripping out micro-transactions features from its iPhone games such as Zenonia and Baseball Superstars because it wants to see how the market develops.
