I have all LOK series games in my Steam library as well as GOG versions, still the experience is not complete as Blood Omen is missing in both distribution systems and all available games are quite difficult to play with the keyboard and there is no support of modern controllers. Right now I think the best way to have all the games is to purchase them via PS Store for PS3, unfortunately no game except for the first Soul Reaver (which i have purchased recently) are available for Russia.
On my question to Playstation support they have reverted with the suggestion to contact Square-Enix, so my question if it is possible to unlock other LOK games in PS Store for Russia as I do not want to buy used hard copies.
