People keep talking about micro-transactions and paid items on online games, but they are 100% focused on MMo games and nothing else.
I’d love to have a few extra units for company of heroes. $10 for 2 new russian tanks and a few new infantry units? Go for it, my fingers are poised over the buy button. I wish I had a single mass-market game that supported that kind of stuff, because I’d love to be able to release ongoing expansions for stuff like Kudos and Democracy. The thing is, such expansion content is 99% fixed costs, and it’s just not financially viable. Maybe the next game it will be.
The problem will always be transaction costs. I’d happily release some new policies for democracy 2 for $0.20 each, but it would cost treble that in credit card processing costs. We need someone like google or amazon to set up a mass market, one-click economic micro-transactions scheme. Great things are ahead when such a system is in place.
