SCPM: Looks like GOG's got a new special promo coming soon:
"GOG.com launch “Mutator Promo”, allow gamers to spin the wheel on up to 3 mystery “mutator” games with each highly-discounted 3-game purchase.
Their Mutator Promo allows gamers to take their chances and pick up three mystery “mutators”, each one for $2. To take part in the sale gamers need to pick 3 games from the promo lineup discounted up to 85% including Theme Hospital for $1.49, Cannon Fodder for $1.19, Leisure Suit Larry: Love for Sail! for $1.49, Outlast for $4.99, Broken Age for $12.49, Long Live the Queen for $1.99. This, in turn, gives them access to 3 “mutator” games – mystery titles that will be revealed after checkout. The $2 mutator could be anything from a $5 game to a $45 one!
The lineup of both regular games and mutators will change completely after the first 48 hours. The Mutator Promo will last for the next 6 days with an entirely new lineup of both regular games and mutators introduced after the first 48 hours."
