I originally thought about getting it from a store, but then I checked the 'origin' website and it says that I can download a game as many times as I want and there's also the possibility to save levels on a cloud storage (or use it as a backup for local files)

so I thought: what if I buy it from a store? how can I be sure that nothing gets lost? can I still save stuff online if I buy it from a store?
and there's also a $12 difference of price (which might not be too much for someone, but it means a lot for me)
