Also, try this KQIII Remake from Infamous Adventures. A very faithful remake of the original KQIII. With full speech support (which can be turned off, btw), it's really like paying tribute to the original.

AGDI is good, but as you might heard it from me before, though the KQ2 remake is very good, it added and changed a few puzzles/scenes, which in my opinion is not really KQ2, especially when you have played the original KQ2. I just hope they won't screw up (depending on my context) with KQIII.
Of course, the original KQ2 has some illogical puzzles, which AGDI tried to address in it's remake. And I'm a fan of AGDI too, since I'm an adventure gamer foremost, and am deeply involved in playing Sierra's/Dynamix' and Lucasarts' adventure games.
Infamous Advetures are also in the process of making the Space Quest II remake :
