[GOG] Good "OLD" games recommandations? (that aren't on steam)

Railroad Tycoon 2 Platinum. Despite being on steam, only residents of a few countries can buy it from steam. GOG's version is NOT region-locked.

blade The edge of darkness (but isn't compatible with windows 10 and you need a patch for play it in windows 7 or windows XP if i don't remember bad

These awesome games are not presented on Steam, but they are worth buying on GOG:

quite a few titles published by gog themselves worth a look (depending on your preferences). highly unlikely they will appear on any other service.

I love Project Eden, which never made it to Steam.

Everything in my wishlist

• Garou: Mark of the Wolves (arguably SNK at their very peak; they had pseudo-3D objects that were animated in the backgrounds)
• Might and Magic series
• Ultima series (Basically the grand-dad of all RPGs. They even were the first online MMORPG ever. Nominate them for best series ever)
• MDK
• Neverwinter Nights: Diamond (removed from Steam yeaars ago)
• Soldier of Fortune: Platinum Edition (has the GHOUL Engine -- basically each body part can be damaged individually, to the point of innards exploding i.e., if you kill someone by stomach shotgun blast, their intestines will pop out)

I'm replaying rollercoaster tycoon 1 & 2 right now, great game. I've never finished all the scenarios as a kid.

Jill of the Jungle: The Complete Trilogy & Bio Menace

Total Overdose

No one Lives Forever 1+2

The original Gabriel Knight: Sins of the Fathers! I've heard it's much better than the 20th Anniversary Edition available on Steam.

I'm not sure how many of these are, but these are some great oldies:
Anachronox (Cyberpunk RPG with ATB)
Dragonsphere (Point-and-Click Adventure with some really unique Fantasy elements)
Heroes of Might and Magic 1-3 (Turn-Based Strategy, a genre that I usually can't stand, but I like these)
I Have no Mouth and I Must Scream (Point-and-Click Adventure based on the short story by Harlan Ellison)
Jill of the Jungle (Platformer that's a little clunky, but it works together very well)
King's Quest (Point-and-Click Adventure; all of them are great, but you might want a walkthrough)
Legend of Kyrandia 1 & 2 (Point-and-Click Adventures with interesting mechanics and great characters; 3 was... not great)
Lost Eden (FMV Point-and-Click Adventure with some interesting systems at work)
Nox (A bit like Diablo, but with better combat; you actually have to think about what you're doing)
Planescape Torment (WRPG that allows many solutions to most situations; combat is almost never mandatory)
STALKER (Open world First-Person Shooter with some really bizarre occurrences)
Sacred (Like Diablo, but open world, and with 8 playable characters; the world, itself, is an absolute joy to explore)
Sanitarium (Point-and-Click Adventure that dives into the character's mind for most of its areas)
Septerra Core (Western-made JRPG with a great cast, very unique lore, and an ATB system)
Turok 1 & 2 (Not terribly popular, but I think they have interesting level design and awesome weapons)

Debatably old games that are worthwhile include:
Blackwell Chronicles (Point-and-Click Adventures about helping ghosts move on; all 5 are great)
Edna & Harvey (2 Point-and-Click Adventures with a warped sense of humor)
Kathy Rain (Point-and-Click Adventure starring a sassy biker chick; she's so cool!)
Layers of Fear (Sometimes called a Walking Simulator, but there's a little more to it than that; great psychological horror)
Painkiller Black (First-Person Shooter with some really over-the-top weapons)

I have tons of others that I haven't played yet, but I've finished each of these and will gladly vouch for them.

Best tactical S-F fleet battle simulator with decent mods to download :)

Sid Meier's Alpha Centauri/Alien Crossfire.

Also the entire Wing Commander series.

Sid Meier's Alpha Centauri and Alien Crossfire
Imperialism and Imüperialm II

The Saboteur
I think that was one of the best titles ever published by EA. Of course they immediately closed the studio developing the game after release, typical EA :(
