Game engine Unity has announced it will begin charging developers a fee every time a user installs their game. That's even if someone's just installing games they already own on a new computer.

For developers using Unity Pro or Unity Enterprise, games “that have made $1,000,000 USD or more in the last 12 months and have at least 1,000,000 lifetime game installs” will have to pay the fee.

It is particularly harsh for smaller developers using Unity Personal, as they will be $0.20 per install if their game makes over $200,000 within 12 months and gets over 200,000 lifetime game installs.

Unity's website states that developers using Unity won't be charged an install fee until their game makes at least $200,000 in revenue and surpasses 200,000 installations.

Unity proclaimed that on Jan. 1 it would be implementing a pay-per-download pricing model to charge developers a flat fee any time someone installs a video game utilizing Unity software.
