Leisure Suit Larry 2
Heart of China
Police Quest 3
Kings Quest 6
Alien Breed 3d
Simon the Sorcerer
Second Samurai - Disk 3 had a read error back in the times when I completed it - not beeing able to see the end-sequence pissed me off! Will try it again someday.
Batman The Movie
Indiana Jones and the Last Crusade (Adventure)
Indiana Jones and the Fate of Atlantis
Dizzy - Crystal Kingdom
Dizzy - Prince of The Yolkfolk
Back To The Future 3 - had a hard time releasing the last brakes on the train. Actually took me quite a few years!
Beneath A Steel Sky
Rise of the Robots
Warzone - also finished after years and years of playing.
Wiz 'n' Liz
Prince of Persia
Right now I'm trying hard to complete Lotus Turbo Challenge 2
- Never completed this one without cheating before
// EDIT Gave up after reaching the last level. Don't feel like remembering where all the turbos are - which seems like the only way to complete the level.
The Chaos Engine
- finished this just now with Brigand (and the computer being the priest). Damn the fireballs in the last level. Wasted a lot of time keeping enough lives left at the end boss.
- finished several times through the years.
