Codemasters released screens of both the 3DS and PlayStation Vita versions of F1 2011 today, so let's be inappropriate and compare the two.
The Vita version launches opposite the system on December 17. The 3DS version follows on December 22.
Both versions have seven modes: quick race, time trial, grand prix, career, championship, challenge and multiplayer. Multiplayer includes online and local play for between two and four players.
