If suggestions are ok:
Can we get a sale on Majesco games (Advent Rising, Bloodrayne, Bloodrayne 2, Psychonaut) soon? I haven't played any of these games, but all four seem interesting enough that I'd purchase them if offered in a GOG sale.
Sanitarium might be a good candidate for a GOG gem sale. I'm interested, anyway. ;-)
Also, I gave the thread a generic title so that anyone else can post suggested sales here, too.
