@Johnnypenso There may very well be many people like who share you opinion with regards to the in game economy and offline mode. But I'm sure that there's just as many like me who feel the complete opposite. Many people want a proper more in depth career mode, as
@Chameleon said, with an array of races for all sorts of cars, that can be enjoyed as you progress through the game. GT3 did this very well with it's vast career mode.
However, with GTS I'll make an exception, as I'm intrigued by the change in direction for this game, what with the FIA partnership and what not. But I'd love for PDI to return to the classic GT format for their next iteration.
Granted, this is a new generation of racing games, whereby the focus is switching towards eSports and online racing, but that doesn't mean it cannot be balanced with a proper offline mode.
