Hmm... Probably not a good idea to admit this but I actually quite liked the mouse interface adventure games...
I still played all of the old text parser graphical/text ones as well but every so often I would get stuck even though I knew exactly what it wanted me to do. I just couldn't get the exact command word or wording right for it to do it.
Weird how before you couldn't get anything but adventure games but now it's all sports sims and FPS style games.

I really liked Monkey Island 1 to 3 and the Indy games. Wasn't that keen on Monkey Island 4 because the 3D system annoyed me. I still haven't actually completed it even though I bought it.
