This is going to be my first GT game. I read some very good feedback so decided to get the game. Anyways i've some questions. I heard there are some update issues that can even make you delete the entire downloaded content (from the store), is this true? How many GBs do i have to download including all updates?. And how does the credit system works? I saw cars costing 1M+ and others only 10k. Is it hard to get credits? I mean I feel like trying to buy a car costing 1M+ credits will be a pain. (apologizes for my bad english)
