BatteryTech has been an interesting experiment so far. In case you don't know what it is, it's a software library I developed last year for Battery Powered Games that makes it way easier to write cross-platform games, assuming they are targeted at PC, Mac, Android and iOS. BatteryTech is not free, but instead goes for a one-time purchase with lifetime upgrades. This model is nearly opposite from most of the competing products which opt for a subscription model, getting you in the door cheap and taking that chunk of change from you each year to keep using their product. It's difficult to figure out what the best marketing strategy is for a product like this, so today I set up the $99 experiment, which I'll explain further.
