Well there is a choice.. i did all the 'less painfull' events like AMG, Top Gear, Nascar, Kart, Licences etc.. and got arround a million credits out of it (with selling the rewards car etc..) Bought myself Eunos Roadster, NSX-R, LFA, 370Z, have the Facebook Jag XJ13, Special Edition Eunos 91 as a licence reward.. and still have like around 400.000cr. Gonna buy more street cars.. so it's plenty of content to play with, until (hopefully) credits are earned through online races..
