I won't pretend to know much about motorcycles, but I do know that when it comes to motorcycle video games you can't go wrong with MotoGP. After missing 2012, it looks like the franchise is coming back, as Milestone Italy announced MotoGP 13 today, coming to PC, Xbox 360, PlayStation 3 and PS Vita. Planned for release in June, the game's tagline says it all, "Speed. Emotion. Innovation." Motorcycles.
In all seriousness, I'm not entirely sure what's been announced. The game's announcement trailer doesn't feature any in-game footage, but it does mention the full "2013 MotoGP Season" which will include MotoGP, Moto 2 and Moto 3. It will also feature several game modes like IRTA Test, World Championship and Career Mode, in addition to "real in-game events," which I might assume is leaderboards and social media.
In summary, MotoGP 2013 was announced! It will feature tons of motorcycle racing in tons of different ways, with tons of motorcycle fun. It's going to be released in June, 2013 across a number of platforms and you can check out the game's website for more information. I'm quite terrible at this. Motorcycles, vroom!
