I have a quest(ion) for you peeps:

Most kids here interact with their first computer when they get to high-school (13yo here), so I want to make a game library of classics and indies for my kiddos age 13 to 18. My idea is that:
1. They have DRM-free fully patched games to play that do not require internet connection to function at a basic level, so single-player or at most LAN capable games with single-player are encouraged. (Couch coop like Worms is fine, too.)
2. They can play something without the present day enshittified gambling boogaloo mechanics, so we can tackle the gambling epidemic a bit earlier from at least this angle,

The list will obviously feature the most accessible from GOG.com's list of Good Old Games, like Fallout 1+2, Neverwinter Nights, Skyrim, Dungeon Keeper, Theme Hospital, Simcity 3000, Civ 4 and Planescape: Torment, amongst others. I'd also add Sims 2 or 3.

Now, what else would you add to that list? Space is cheap nowadays, so if you suggest a game it will almost assuredly be added to the game library for these kiddos to enjoy.
