#10 is some sort of Star Wars FPS. I'll guess Star Wars: Dark Forces.
Star Wars: Dark Forces is my game #10, as guessed by The_Liquid_Laser.
I already had some Lucasarts-games in my list, but they were point-and-click-adventures. This one is an old-school first -person-shooter. And while Dark Forces builds upon the foundation of basically Doom it improves the formula in many regards and has a consitent world. Also Dark Forces adds mission briefing between the levels, which puts you much stronger into the plot and give you a stronger feeling for the goal, instead of just finding blue and red keycards and finally the exit. Dark Forces has for each level a clear objective, for instance in the first level recovering the blueprints for the Death Star. This makes the game so much stronger than Doom.
The shooting gameplay and resource-management (shields, ammo) works well. The plot is fine and grows good, as you explore more and more the threat of this new development. You play as Kyle Katarn, a new character which allowed Lucasarts to develop a new story.
The game should work fine with Dosbox if you have an old copy, but I can't find a way to get it now, as GOG only has Dark Forces II, which is already very different.
