Some discussion about a direct control interface vs. point and click sprouted up in this thread and it made me wonder which direct control adventure games you guys have played, and what your experience was with them.
The first one I remember playing was Gabriel Knight 3 (well, not counting the old King's Quest games where you walked around using the arrow keys :D), and I had a terrible time with it because I don't have a very good sense of direction and had a hard time figuring out where the camera was pointing and which way to walk to make Gabe go where I wanted him to go. In that game you can actually set the cameras to behave in different ways and I finally figured out some settings that worked a lot better for me.
It's funny though, because right around the same time I played Final Fantasy 8 on PC -- which had a very complicated keyboard system -- and it wasn't so bad. It may have helped that you could remap the keys. I don't remember if GK3 allowed this. Shadow of Destiny is another one where I got the hang of the controls pretty quickly, although I do remember the cameras behaved differently when you were inside than when you were outside, which was confusing.
A few years ago I got a gamepad and I was amazed at how much more fun it made direct control games for me. It also seems like people who are more comfortable with action games have an easier time than people who aren't. I usually play adventures with the occasional RPG thrown in, so I think that's why it took me a while to get the hang of direct control.
Anyway - that's my (longer than originally intended) story. I'm curious to hear some other opinions...?
