I'm now trying to buy games from Steam I already own.
If you had to quickly summarize your collection,
How many games bought from STEAM sales do you have that you haven't touched yet?
right now, if you buy the game as a gift you can either trade it or give it to yourself. there are a few people using steam trading to get rid of extra copies. you cant trade played games ......yet.
the EU rulling on DL games not being licenses will eventually force valve, gmg, origin etc to allow you to trade 'played' games directly to others. so even if you installed and played a game you will be able to sell it to another person.
so at least in europe multiple copies wont be a problem. since operating 2 version of steam (one for licensees and one or 'owners') isnt worth the international lawsuits the US users will likely get the same resale rights.
I've got two entries for the Civ IV stuff, too. AFAIK this has nothing to do with buying the game twice; it's just listing the Mac version as well as the PC version.All I can say is I'm damn glad that it now stops you from trying to buy stuff you already own (except in certain circumstances). It's saved me from buying stuff twice a LOT. The only thing I got burned on that I can see in my library is Civ IV. I have entries for every component twice, which means I paid for the whole taco twice as separate items... once as a bundle, and once individually.
