retsushi: Bioware don't care about this game.
Bioware is dead. On the other hand, they cared enough about the game to make free updates and even integrate community patches into free updates well after the game was making them any money. It's a pity that the free Linux binaries that they hosted until their demise have now disappeared.
retsushi: Beamdog didn't make this game, they work on this game. But Beamdog crew used to make the game 15 years ago.
But what work? What are they trying to do? The last team that wanted to improve NWN made NWN2. If Beamdog is really interested in improving the NWN experience, and they actually have the old NWN team as you claim, why don't they just make NWN3? It's not like they don't own the rights to do so, unlike anyone else who might want to make NWN3.
Did they really work on the game 15 years ago? I see no proof of that. Your original statement, and this as well, implies that the majority of the people who are responsible for what NWN became are currently working at Beamdog. Do you have a list? I see lots of names in the credit list for NWN (not counting the expansions), and only one of them definitely works at Beamdog. It's hard to say how much of an influence the CEO had/has on the game's design, but they are always listed in the credits, anyway.
In fact, if the people who are responsible for the game are actually working on this, I expect a lot more enthusiasm, and plans for a much more ambitious improvement. Take Wasteland for example. Yes, Wasteland 1 was re-released with only superficial improvements (well, I hate to have to always look stuff up in the manual, so for me, the improvements made the game more playable). However, they didn't do it just as a cash grab -- it was part of a larger plan to release Wasteland 2.
Instead, Beamdog treats the games like some sort of sacred gem that will self-destruct if they do too much work on it. This does not sound like the actions of someone who is intimate with the product.
