Aside from the number of online players, are there any differences between the current and next-gen editions of Rivals?
The visuals are quite different. These new machines are really powerful, more powerful than we initially thought they were. Visually, they're equivalent to very high-end PCs. It's really cool to be able to have that kind of experience on a console.
With that power we can make the game come alive to a whole new level. We've got great particle effects, waves crashing in over the top of cars, all of the things racing games haven't had in the past
