Driveclub was supposed to be one of PS4's flagship titles to attract more consumers into buying a PS4 instead of Xbox One. Obviously there was a lot of promise in this game. So much so that this game was suppose to come out on PS Plus for free at one point, but never did.
Not only that, but the server issues were also extremely problematic, as many players complained in gaming forums everywhere. That doesn't make Driveclub a bad game though. It's a decent racer with the same type of gameplay that racing fanatics are comfortable with.
However decent this game is, it's still disappointing for not living up to their promises.
