I'm just curious today if a game like BG2 would be as popular today as it was in its time. Is a toolset necessary for a crpg to sell, or would people go for a game that did not have a toolset attached?
Essentially, game development only has so "zots" to spend. If a ton of those zots are spent making a new engine and an associated toolset, the campaign must get less time. I think that's a big reason why official campaigns have become much shorter recently. On the other hand, if someone were to purchase the rights to use an existing engine, more time could be devoted to the story or companion development. In other words, perhaps a sixty to eighty hour campaign with fifteen companions would be possible versus a forty hour campaign with only eight companions if the engine had to be built too. I don't know if the community would support that anymore, so consider this my way of unscientifically polling the community.
Oh, and this is just for my own information. Don't read too much into this.
