These are the games you have purchased and have in the shelve? Probably not but... My god, we posted at the same time!?

Well, actually it's says "posted 2 minutes ago" on my post, and "Posted 1 minute ago" on yours. While I'm typing this. :) So almost.

Ah, ok, I tought it was at the same time. This happened before, Tantrix and other user posted and when I tried to quote him it appeared the other user!

My guess is they all have support for Windows 7

Thanks for the contest! I enjoy having arbitrary problems thrown in front of me even though I often have no real chance to solve them (actually especially if I don't have a chance) The best part is seeing what the solution is and how I could have figured it out "if only ...."

These are games you bought when they were first released and have bought them a second time on GoG?

The comment you left for each game is the same.

They all have some kind of shining light source in the art

They are all DRM-free =D

Given that the OP has an orange avatar I'm inclined to agree :P

I have no idea. It's either the orange color theme or the alphabetical order thing.

But I'll say they are all compatible with Windows XP.

Just a stab in the dark here since I've only looked at a few of the games on the list, but I'm going to say the original developer of every one of these games has since either gone under or been bought out.

I'm going to go with the obligatory "trick question" and say that the games have absolutely nothing to do with eachother.

They're all on the list you made for the contest...

My answer is that the only language they are available in on GOG.com is 'English'.
