I did it! I finished Space Quest I without having to go back to the beginning to pick something up again.
After the last session where I had to go back and pick up the knife to open the grate, I progressed through the enemy spaceship until the end. I loved this part. Talking to Marvin, I mean the depressed robot. Shooting the near sighted aliens, and doing to them what they did to us, namely self destrucing the ship. It’s a proper way to end this adventure.
This game doesn’t overstay its welcome and that’s good. For any future Sierra adventure games I learned that if I’m stuck, I need to replay the whole game again to make sure that I didn’t forget to pick things up. That way I’m sure I’ll enjoy the game even more than I did this one. This was great! I’m glad that I now can say that I have played this important game in point-and-click history.
