6. Forza Motorsport 5

Alright, so the chances of Microsoft releasing two racing games at launch isn't exactly high, but the Forza Motorsport series has pulled ahead of Project Gotham in recent years thanks to its silky smooth gameplay and astounding visuals, basically making it the Xbox 360's answer to Gran Turismo (if still trailing a
little behind). Whether it arrives at launch or not, we know for sure that a new Forza is in development - owing to a job listing posted last year - though various rumour websites have reported that Forza 5 is aiming for a launch day release, and will boast the most life-like visuals yet seen in a racing game. That's quite the claim to make, but with the 720's potential technology, we might just get blown out of the water yet.
