Eurogamer - What happens when free-to-play games aren't free?
A little too open, it turns out. There are aspects of free-to-play design in the bulk of the Xbox One's launch titles: Ryse has microtransactions that aid progress in its multiplayer mode, while Crimson Dragon's single-player path can also be given a little helping hand by buying in-game currency with real-world money. Elsewhere, Forza Motorsport 5 allows you to boost the rate at which you gain XP for a little extra cost, or to spend money to fast-track your way to a higher end motor. They're all systems proven in the world of free-to-play, but there's a problem: none of these games are free.
