I played KQ3R to the pirate ship yesterday and it is a pretty impressive remake. Not as full scale like KQ2 was, which went a bit too far IMO, but a reasonably polished and more well rounded.
There's a couple of new puzzles made in the first half and the pirate ship part seems to be a bit different as well from the original, so it's not 1:1 remake like the IA's remake was. The background graphics are amazing.
My only real problem is, that AGDI still doesn't have a good character portrait artist. Most of the character closeups look pretty horrible IMO. But that is just a small peeve, otherwise the game is very good.
