Hehehe ... Funny enough there is a lot of personal motivation here at GOG.com, as we would love to play these games ourselves. Arcanum was really great and I still remember our collectors edition of Temple of Elemental Evil (CD Projek was the polish distributor and we did full localisation to polish). Good old Days :)
Arcanum is definitely one of my favourite games, and VtM: Bloodlines is also really good with Wesp's unoffical patch. I've never played ToEE and it doesnt seem to be exactly the kind of RPG I prefer, but I'd gladly try it out of curiosity.
And yes, I wish you guys could get more of these games you've localized to Polish... Planescape <3 Torment, Baldur's Gate saga, Icewind Dale games.. just look at where these games are on the wishlist ^^
Hopefully these localizations have given you useful connections :)
