Recommended game's? (What's Your List?)

Many people here suggest main stream games or recent games. No love for oldies and gooldies?

Like what about the epic RPG series Gothic? I still rock Gothic 1 and 2 with tons of mods around. There are mods with massive stories for over 200 hours of playtime. The quests, worlds, characters and everything is generally very nostalgic and feels way better than nowadays RPGs. The classic touch is really nice and at the same time the game has a mod for full DX11 support with sick textures and graphic mods like L'Hiver.

I easily burned hundreds of hours with these two games and right now playing the mod "Odyssee" for Gothic 2 with 100 to 200 hours playtime from all the quests, chapters and etc.
