Sure did, SR2 and SR:Defiance. I think SR1 was the best in terms of gameplay and story. Felt a lot like a zelda game to me with discovery, exploration, new areas opening up as you gain abilities. SR2 in my opinion was a great game too, just didn't like it quite as well as the first since it's a direct continuation of the story and there isn't so much 'new' to enjoy. The combat did get some improvements in the second though as I recall, a few new things you could do which I appreciated, but almost seemed like combat was given more attention relatively to the puzzles and story. In the 3rd aka Defiance there were some definite graphical improvements and the story was nicely brought round to give an ending and some explanation of past events, but the twist of switching between the characters made it feel a bit disjointed gameplay wise imo. As I'm sure you're aware the Blood Omen games, while they share the mythos as the Legacy games, are considerably different and as I understand it were made by a different team. Would still like to see the first one here on GoG to complete the series - voted for it on the wishlist Blood Omen if you want to cast your vote.

I'd put Legacy of Kain: Soul Reaver 1 at a 9/10, Soul Reaver 2 at a 8/10 and Defiance at a 7/10, Blood Omen 2 is probably the worst of the bunch since it has much less in the way of puzzles and different setting and no phase shifting (but then I didn't play through it to the end so don't want to give it a rating, maybe it got better :-))

Recently picked up Blood Omen 2 on GoG as I only ever got to play a little of that (rented as opposed to owned) so I'll have to go back and play that one in it's entirety. Plus I recommend using a controller if the windows port allows for it (or mapping controls if necessary) since these games plus a few others like Prince of Persia (not the original ones but the remakes) seem to play more intuitively with a controller imo.
