Forza Horizon 2 vs. Driveclub. Which game will sell more?

[GribbleGrunger]

I'm assuming you mean Horizon on the XB1? It wouldn't be fair to include the 360 version.

I'm going to say Driveclub but it's going to take quite a long time to determine how many it sold. It will probably have the highest digital sales of any PS4 game to date.
