Zookie: I am a big fan of GOG. It is by far my favorite digital distribution site. But Steam has always, and is likely to remain so for the foreseeable future, the 800 pound gorilla in the room. What do you do if there is a game on Steam that you really want but you are unable to get it elsewhere? I have never thought much about this until the Homeworld Remastered release.
Do you just buy it on Steam and just let the lost potential revenue for GOG to be a motivator to add the titles that are being bought up at other distributors?
Do you buy on Steam and then later, if GOG gets it, buy it again to support GOG to support its DRM free philosophy and its focus on resurrecting old games?
Or do you refuse to support Steam and just hold out and buy the game you want when it shows up on GOG or another a less draconian distributor? Regardless of the time it takes?
Personally, I'll wait until it either shows up on GOG (preferred) and hits a seasonal promo sale, or secondly I'll wait until it either shows up in bundles in a year or whatever or it shows up on 80% off on GMG with the 20% bonus coupon.
