Sorry to hear about this. I bought these a long time ago now fortunately but I hope they can be returned for sale for other people.
I have come to feel over the years that whenever something important to me becomes available, I shouldn't waste too much time grabbing it once it hits a sale price I'm happy with just in case because these things do happen sometimes. I've been pretty lucky so far taking this approach although one time when I did get caught with my pants down when XIII was pulled, a very kind person gifted me a copy in the nick of time. That time we had a little warning beforehand though.
I missed XIII, Re-Volt and Colin McRae Rally completely and wonder if they ever will be in my library. :(
Damn, I hope they'll come back.
I wish I had picked up a GOG Re-Volt myself although I think my original copy of the game still works. I got that game many years ago when I bought my daughters their first computers of their own and setup our first home network using an Intel network that used the house wires if I recall correctly. There was no wireless home networks back then. I did that in response to them constantly camping my computer to play my Asheron's Call account which they took over on me. Nothing was sacred. Those girls took my clothes, my camera, my videos at times, my computer, played my game. I was a serf in my own castle!
To give you an idea of how long ago that was, both of those little girls are all grown up now and have completed their master's degrees and are professionally employed. I am even a grandfather now thanks to my oldest daughter.
Anyway, at the time I remember Re-Volt being great fun. I had a blast with that game. I remember too that the graphics were awesome, at least for the time they were. I hope it returns to GOG too. I'd buy it in digital form.
