Anything not related to one of my specific games, like general polls or promo/sale announcements. For general talk about games, go to the Golden Lion subforum
In practice all games released this year (except Never Forget Me since was just released) are 20% off, while older games are 50% off. Offer lasts until end of year.
My games are on sale also on Steam. Depending where you live (Steam do country-based prices, while I cannot do this on my own site) it might be cheaper to get the games on Steam or on my own site. No matter where you buy them, have fun
