That's such a shame. The more distributors the better.
I know what you mean re' support. I purchased well over 800 games from Reflexive arcade over a period of about 3 to 4 years. I only changed distributors because I discovered and liked the Alawar registration method better. Anyway, when Amazon bought out Reflexive a few years back, they gave until July 2010 to ensure your games were installed and registered. After that date it wouldn't be possible. That's fine if you were able to copy the registration code and use it globally on any computer. The problem was, once you changed your operating system or upgraded your computer with a new cpu, motherboard or hard drive, the registration code no longer worked.
Thankfully after over a year of occassional searching I used what could only be described as an illegal registration code generator. Now I can re-register my games any time I want apart from a few that used a different coding method. What's annoying is that Amazon basically washed their hands of any responsibility once the deadline ended last year. Though I was later told they extended the support but I don't know for how long.
In the UK, if you purchase a company you are then held responsible for the promises that were made by the previous owners to previous clients; in this case unlimited registrations for the lifetime of the license holder. Though in reality that has never worked because they had a get out clause which involved liquidating your company and reforming under a different name.
This is what worries me about digital downloads as opposed to owning hard copied. Also DRM activation. Are any of these distributors safe? Refelxive should have created patches for all those who'd purchased licences, especially considering that most of the game purchased from them were before games started to become cheaper. That is I paid $19.99 for each game. That means I spent around $16 000 on those reflexive games over a three to fur year period. (I was too intent on trying to distract myself from the ever present pain once I'd discovered that games really helped with pain management to realize how much I was spending. Morphine tends to take away self control (well it did for me, lol))
