[quote name='hal']I wonder if any of those will be allowed to be redeemed as credit at some point? I already have Unstoppable Gorg on Steam (good game, btw) and I'm thinking I could net a few bucks towards future purchases.[/QUOTE]
Well, I'm not allowed to use my powers of divination outside for free, so I'll just point at the past history of GMG freebies (which have small, sometimes larger trade in value, it varies.).
As a racing junkie, I'm interested in the racing game. I might give the zombies game a try out of curiosity (I think I passed on it in groupees.) I backlogged Ninja Blade for $5 on the Steam Summer Sale (I see it as the highlight of the giveaway). I can't say that Gorg has any appeal to me.
