The End Is Near: Gamestop accepting retro game trade-ins

[E-Man]

That's a very good question. I think that it might be resolved if you actually downloaded the games onto your computer instead of relying on cloud data, but this is only a guess because I don't really know ho Steam works for certain.

Anyway, what I could tell you is that Steam might have already taken precautions to prevent everyone in the whole world losing their games (i.e. backup servers) since I think that a big company like that gets asked that question at least on occasion and it is a smart business move to invest in a backup plan or two.
