User blog comment:DerrickMa5/What will be different with Asphalt Nitro than Asphalt Xtreme has?/@comment-72.1.21.70-20160429105859

Nitro is simply a dumbed-down A8. It recently got an asynchronous Rivals mode, but that's where all difference ends.

Meanwhile, Xtreme appears to be an off-road Asphalt.

Sorry if I'm a little early.
