Well, that's a shame. But there are obviously a lot of people who are willing to pay 50 euros (or $50 -- what's the current exchange rate, anyway?) for a game without a toolset.
The economics of including toolsets are questionable. There seems to be strong price resistance to anything over $60 or so, toolset or not. They'd have to get a lot more sales from including a toolset to justify doing the work.
Assuming LA would let them do that in the first place, and I'm not sure they would.
Yet all this didn't stop Bioware to create/release their Aurora Toolset to the public. I've created hundreds of areas/quests and I still enjoy doing it.
Sure, the learning curve was (or is) pretty high but I still managed to learn bits and pieces and created lots.
The things that can make a game more interesting and/or last much longer then the average game is a Toolset/Worldbuilder or whatever you want to call it.
KOTOR was lots of fun when I started playing it for the first time. I probably solved 95% of the quests. Then I started a new character but (to me anyhow) most characters are alike.
50 Euro is alot of cash and I don't have a tree with money growing on it. Once KOTOR 2 has been released then I'll have a look at a friend to see how the game really is. I think 50 Euro is about $48
Games are getting more and more expensive and there will be a time when I will stop buying games and only be able to play them a few times before they become boring.
Ah well...
