you missed kagura games out
"NEWS: Publisher Sale: Kagura Games with their NSFW titles discounted up to -75"

Defender's Quest is on sale (50% off). The last time it was on sale was July 2019.

Just curious: what would you consider your minimum "gap of time" amount? At least 6 months since a game was last on sale, or somewhere around that?

One question, you guys have an info on what the highest discount rate that these two games usually have during sales? Thanks!

Terraria
Ground Control II

(Some of you will probably say just buy the game at the current price, but I also still want to save my money as much as possible lol)

Terraria 50% off (4.99 USD).
Ground Control 2: Operation Exodus Special Edition 66% off (2.03 USD).

Oh damn, thanks for the quick response. :)

Yeah, my personal rule of thumb is six months since the last sale.
The exception is if the game is on sale for the first time in its history on GOG (not including if there was a release sale), then I tend to set it at three months since its release date.

Screamer 4x4 is on sale (70% off). The last time it was on sale was January 2023.

Doctor Who: The Lonely Assassins -65%

Looks like the first time it's been discounted on GOG since its release in 2021

No, the highest on Terraria was 75% off (2.49$).

Highest discount on Terraria was 80% off few times in 2014. Since 2017. it got stuck on 50% off each time it goes on sale.
