I'm generally pretty much in agreement with the idea that online services are crap because you don't really own the things you buy, but honestly I've been buying physical media since the 80s and pirating since the 90s, and the oldest games I currently have easy access to are ones I bought on Steam. I'm not a collector or an archivist or anything. Those just aren't hobbies that interest me, and I move a lot, and don't always take care of my stuff, and freely lend things to unreliable friends, and frequently wipe my drives to try out new Linux distros, so at this point even if Valve probably won't be around forever I still expect my Steam games to last longer than anything else I could get. Steam is really the only reason I ever buy games at all anymore.
