This price is very close to the lowest ever price according to ITAD. If you spend more than $2 on the store (which you will if you buy Project Cars) then you will also get a free key for The Last Tinker: City of Colours which is itself a pretty, fun, and enjoyable game.
So, if you want to play Project Cars any time soon and have not already got it through a monthly bundle, then here is your chance to grab it at a reasonable price and get another fun and good game as a bonus.
Enjoy.
I believe it's actually The Last Tinker: City of Colours. And it is a truly brilliant game, similar to the earlier Spyro games.
