Apparently Obsidian CEO Feargus Urquhart is feeling nostalgic lately. First it's his public campaign to win an Icewind Dale sequel. Now this:
OK, clearly this is just blog fodder. Urquhart seems to be humoring the interviewer - based on the quote, he doesn't strike me as being all that thrilled with the idea. And why would he be? The original game's ending is about as final as you can get. And by now it's so old that only ancient gamers and true RPG connoisseurs have played it, and only a subset of them would like to see a sequel (for some, it would be akin to making Citizen Kane 2). And on top of all that, PST apparently didn't sell all that well. Other than that, it's swell idea.
“I remember right after finishing Planescape: Torment I spoke to Chris Avellone [Obsidian creative director] and asked what he wanted to do, and he was like, ‘I don’t wanna do a sequel!’ We haven’t talked about it in ten years, but it might be different now. But a lot of revisiting old games is about saying, ‘okay, that worked in 1999, what would work now?’ And how would you do it again?”
But still, as a topic of conversation, I find it irresistable (I did say it was blog fodder). In my post about a potential Icewind Dale 3, I ran through what I thought were the essential elements of the original that would have to be continued in a sequel (hack and slash, full party creation, etc). In contrast, I don't think the hallmark of PST was a particular style of gameplay. It was more about the story, characters, and - probably most importantly - the setting.
The challenge in making a Planescape 2 would be one of narrative design. The first game was brilliantly intricate, and featured
That said, problems of narrative design are always solvable when you have smart writers, as Obsidian does. The Planescape setting is in many ways a writer's wet dream, precisely because it's so "out there." The lack of verisimilitude provides a smorgasbord of options, which I'm sure would allow writers to come up with a story that connected to the original without trampling on continuity. It could be done.
The question is, should it be done? You tell me.
