No real order :
- Sternenschweif (Startrail)
- Indiana Jones & the Fate of Atlantis
- Monkey Island I
- Zanzarah
- Cultures
- Tropico
- Die Siedler (The Settlers)
- Age of Wonders I & Age of Wonders : Shadow Magic
- X-Wing & X-Wing Alliance
I think that's it. I would add PS:T, but I've never played it through this far, but plan to do it when I have a new PC. Which might take a while. I don't think it would be that good to add a game that hasn't been played fully through ... although I must admit that I haven't completed the campaign of Age of Wonders : Shadow Magic as well.
And i think I would add Gothic, too.
I liked Syberia very much, too.
