I'd donate very good money to a Baldur's Gate III kickstarter.
Thing is, why Baldur's Gate? The Child of Bhaal storyline was possibly the coolest idea in any CRPG, but that's not what made that game what it was. If Wizards of the Coast really said that, then they have a point. I can't imagine keeping a BG3 true to its origins and ALSO making it sell.
So a Kickstarter game is a game for the fans, right?
Why not just make ANY Forgotten Realms game? Write a new story, but make it a hardcore D&D game - maybe even isometric, like Wasteland 2 is doing.
Well, unless Wizards refuse to sell the D&D license as well. In that case, it'll probably never happen. The longer they sit on that, the less will people care for FR. I think Dragon Age was a bit bland, and it was the supposed "spiritual successor." Re-writing all the lore of an entire fictional universe must be a lot of work. And the re-imagined combat systems are usually... clumsy.
Still, I have faith in Obsidian. They make good games. Buggy or no, I still prefer them to any other RPG developer that's around these days.
