I can't remember what the specific puzzles in Space Quest II were that I got stuck on. I think the first one was probably still down on the planet. And I can't say for certain now why I was able to finish SQ3 so quickly. I guess things just seemed to flow. I certainly finished SQ3 quicker than any other Sierra game I played, by quite some margin. The others took at least a few weeks, if not months.
This was obviously back in the days before the Internet, and I hadn't yet discovered BBS boards either, so it was just me and my brother trying to work it out.
That's amazing you guys got through that game so quick with no outside help. They did sell hint books that started off blank with a marker to uncover the hint. I got one for most games I played. As a rule I'd get stuck on some part for more than an hour, come back a day later, and still be stuck, then I'd uncover a hint. Generally using it a half dozen times to get through a game.
