Well apart from the fully animated ones I've only played Dragon's lair 3D and Dragon's lair 1 on the C64. I guess you could say it's a bit similar. You've got full freedom of movement and that sort of things. Hidden treasure to find in each room.
They did the conversion from many of the sequences in the animated one quite well. Having to jump around the energy shooting through the floor by the knight, fighting off goons. Rooms falling apart and so on.
Still annoys me that I couldn't get the gold goblet early in the game. It's right there on a bookshelf but the floor collapses around it and I don't have time to get it.
