Briareos262: technically they weren't open codes. There were in puzzle form like many of the other previous posts. I'm not gonna say any more as I don't want to get into any debates. I haven't had a day off in 3+ months and its my last day off today so I just want to relax.
You are right they weren't really open codes but it still results in just a couple of people saying thanks while the rest goes to leechers. Also I certainly understand that being busy you wouldn't have time to giveaway each code on a first reply basis which is also not fool proof without a few rules. You can also donate codes to TBBBBoB where Sachys and foxworks would take care of the fair distribution of codes on your behalf.
Apologies if my earlier post sounded like a demand instead of a request, all of these are merely suggestions and in the end the games are yours to giveaway in whatever way you choose to do so. Enjoy your day off. :)
