Parvateshwar: I'm going to have to vote No on a new Planescape. Obsidian has a bad tendency of making mediocre sequels to excellent games, NVN2, KoTOR2, Fallout: New Vegas (I consider it a sequel because Fallout 3 was a sequel to Fallout 2 in the same was WoW is a sequel to Warcraft ToC).
It's funny/interesting how people's experiences with Obsidian's games differ -- as much as I enjoyed the original NWN's Hordes of the Underdark expansion, I felt the vanilla campaign and Shadows of Undrentide were very weak and consider NWN2 and its expansions a
much better series overall. The same goes for Fallout: New Vegas vs. Fallout 3 -- I got bored with FO3 pretty darn fast, but love FO:NV and am very impressed with the DLC's they made for it.
Planescape was a game where you could play with any style and still be rewarded with a unique yet successful game. But with the modern FPS having sabotaged every genre, especially the RPG, I have little faith that Obsidian would treat story, character development, and alternative quest lines for different playing styles on the same level as the combat. My second concern is the diluted level of detail. Modern RPGs need a ton of recorded dialogue to reach half the level of detail in the text based Planescape. In order to come close to the level of detail in the original they will have to put together the largest amount of recorded dialogue for any game to date. Unless they opt for text based and completely sacrifice the 18-24 demographic I doubt people out there should get too excited about this.
I have never considered Obsidian being a developer aiming for the "18-24 demographic". Their stories, characters, and themes have always felt deeper, more mature and more interesting to me than what most other developers are putting out today -- especially companies like BioWare who, for the past 5-7 years, have been blatantly obvious in their attempts to make their games appealing to EVERYONE and their grandmother, their blind dog, and their retarded cousin jimmy. I also think that aiming for certain demographics, opting for full voice over, making stuff "actiony", etc. are things that make publishers drool... And seeing how a kickstarter project would allow them to develop a game "without having to argue with a publisher", as Chris puts it, I think that kinda stuff would not really affect them here.
I want a game like the original Planescape without it being a sequel, but I fear if Obsidian went through all the trouble to get a Planescape game up and running they would lose sight of the core fanbase and instead chase after the wallets of the rabid Microsoft FPS fanboys. They would be better of starting with a blank slate and creating a fantasy game aimed at the 30s demographic who still enjoy the late 90s isometric RPG. If Chris Avellone pitched a completely new game concept I would be interested, but until that happens I'll not hold my breath over this.
I think that Obsidian is the most likely candidate in the industry today to do what you suggested and, again, I don't really understand where your impression that they're the type of company that would "chase after the wallets of rabid FPS fanboys" comes from? Either way -- from the comments to Chris' blog post it seems most people agree with your suggestion (and so do I) so we'll see if anything comes from this. The key here is that it would allow Obsidian to make a game that they really want to make, and that the fans really want them to make, without any of the usual publisher hassle. There's great potential here.
