UPDATE
Finding Paradise (20%)

UPDATE
Niche (10%)

There you go, I've replaced the ampersands with fullwidth ampersands. Or just copy-paste the character. That's what's been done elsewhere on the forum, too.

Also, in pretty much any "Edit" menu on macos there is a "Emoji and Symbols" option, usually near the bottom of the menu. In the panel that appears, I search for ampersand and one of the results is named "fullwidth ampersand".

Here it is again: ＆

I see some missing...

Are these permanent series discounts?

I recall when i first joined the D&D (Balder's Gate, Icewinddale, Demon stone, others etc) had a heavy discount, but i think it happened to be during that week...

All of them kept for a reasonable long time.
Some series adjusted or canceled discounts, but most of them never changes since I made the list.

Users who own Tyranny on GOG.com or will do so before March 31st, get a 10% discount on Surviving Mars.

UPDATE
Pizza Tycoon (15%)
It was 17%. The change is due to the release of Pizza Connection 3.
