I'm trying to clear some space on my HDD, but I'm not sure how this works with DLC. Can I re-download ANYTHING for free, as long as it's in my download history? What if something was free when I initially downloaded it, but has since gone up in price?
For example, I never bought Lumines, but I got some DLC for it that was free during a brief launch window, in case I ever got around to buying the full game. If I deleted that DLC, got the game at a later date, and wanted to get that extra content again - would I be forced to pay for it this time, or could I just re-download it free of charge?
