We do it on a case by case basis. Depends on how many people are requesting it, how much the game costs, how often does it update, etc. It costs us several hundred dollars (each) to create/update trainers and it adds additional workload on our team to now have to support multiple distributions of the games when they patch. So, I cannot promise you that any one game will always receive a trainer for a separate distributable.
Bear in mind that a lot of the old games on GOG run in DOSBox which makes it almost impossible to train them.
I already tried (requested) games like Star Wars X-Wing-Series or Syndicate Plus and Syndicate Wars.
However sometimes a trainer for the retail version runs fine with the GOG version.
Any member that has a valid Lifetime PLUS on December 25th, 2016, will receive a bonus 25,000 reward credits added to their balance. These can be used with our requests system to determine which games get trainers made and we're also working on new ways to spend them such as alias changes, custom avatars, profile headers, custom ranks, etc.
MeRRy Christmas to all.
Your email prompt spurred me into action. Already a lifetime member, upgrading to PLUS is the best thank you to everybody concerned I can give.
