Also, do we reckon there's going to be more spinoff games like Tactics and New Vegas?
I'd love Obsidian to do another Fallout game.
It's a bit uncertain where they're at at this moment, I think. One of Obsidian's main links to the Fallout series, Chris Avellone, just left the studio. Some of the rumours of where he's going includes possibly joining up with inXile and Brian Fargo (one of the original producers of Fallout) to work on a Van Buren-inspired project - van Buren was, for those who don't recognise the name, the codename for Black Isle's cancelled Fallout 3 project which was headed by Avellone and Josh Sawyer. New Vegas was basically their attempt to make that Fallout 3 again, and lots of Van Buren ideas went into it, whether directly as content or as world fluff.
Of course, it would be ridiculous to think a new possible FallObsidian game hinged exclusively on whether Avellone is there, especially since he has been known to cross-work between studios writing-wise (and iirc he only worked on New Vegas as a writer anyway). But it might influence the possibilities.
I'm also not sure in what situation Obsidian is currently in. If I understand things correctly, they were basically on the verge of bankruptcy when they launched the PoE kickstarter and had at the time had to cut themselves down to a very small studio. I'm not sure if they've grown enough to be a multiple game project studio again, but if they haven't they might be focusing all their workforce on PoE stuff in the near future. We'll see.
Maybe. Hopefully they'll get Obsidian to do it again, they did great with Vegas. Hopefully Bethesda will give them a bit more time and leeway, though.
Hehe. I'm a big Obsidian fan, but when you learn that only two thirds of the originally planned map ever even made it into the game, and even then with lots of cut stuff in them, you realise those guys have no sense of scale
