A racing MMO (For those of you that like games and driving cars). Every game that has tried this online has failed for some reason. This one looks amazing and has huge area of gameplay (The whole US). looks like its on every platform too. heres my link to it - http://thecrew-game.ubi.com/portal/en-US/home/ and a video of playing it at pax east from MMORPG.
I have played a few online racing games and the one thing that is a big turnoff is lag. Lag in games like EU is not nice, but it is not a huge problem if it happens once in a while. If you have lag in a high speed racing game, you are likely to end up in a fence or tree and loose your race and potentially your car. This could work, but there need to be other stuff to do than just race. I mean why not have the possibility for someone to paint your car (for money, or credits). Provide templates that people can paint in Photoshop and import back into the game. Fully customize your car and not just slapping a different exhaust on in, but really customize and tune it (turbo pressure, suspension height, brake balance, engine timing etc.)
