I am looking for a Price Tracker / Pricing History tool to find the lowest price for a given title in the past years.

For example for these titles:
Screamer
Screamer 2
MDK
Battle Chess Special Edition

Is there a tool for gog.com similar to the excellent steamdb.info for steam games?

Thanks a lot for your aid in advance!

I think this thread is what you are looking for:

One of our members (RWarehall) made this Google Docs:

There's also MaGOG, which, I believe, shows this info as well: http://www.an-ovel.com/pages/magog.php

I think this was the best Inerplay offer on Gog .

Ave Caesar!

Thanks a lot, the GOG Database ( gogdb.yepoleb.me ) is exactly what I was looking for.
A real pity they only started in June 2017...

Thanks djarko for the link to the awesome spreadsheet!!!
Thanks GR00T - MaGOG is an awesome site I knew before, but does not show prices of past discounts, right?
Thanks Painted_Doll - I think you are right about MDK, but how about the Screamer series?

MaGog shows the best previous discount, I can't remember if it gives dates or any other info though.

Isthereanydeal.com also tracks price history for GoG. It has the limitation that like MaGoG that it cannot capture bundles. It also is screwed up on a few games with long titles + special editions where the prices for the regular and special editions seem to get intermixed in the same charts.

But Painted_Doll has it right. That was a sweet deal for all the Interplay games at 90% off if you owned and/or bought at least 9 of them.

Screamer was also available for as little as a penny back in Nov 2012 when GoG had a tiered promo with 8 games in Tier 1 PWYW as little as one cent.

It should be noted that the following games have never been on sale before (they were released since the last great Interplay bundle):
Ignition
Lost Eden
Of Light and Darkness: The Prophecy
Pray for Death
Titus the Fox: To Marrakech and Back

your link is super dead.

No shit, it's 4 years old.
You can either check https://www.gogdb.org/ or https://isthereanydeal.com/ logs all prices and allows to filter by stores.
