Loom just clicked with me for some reason. It was the first adventure game I completed 100% on my own, and I did so fairly quickly.
The other adventure games I had played to that point I was only able to finish by playing in parallel with several friends and when one of us got stuck, we would help each other. Hero's Quest was the first game I completed in this manner (we were stuck on King's Quest until someone downloaded a hint guide from a BBS; that game was primarily difficult because how easy it was to get in an unwinnable state).
