As long as this doesn't interfere with my Obsidian SCI-FI Kickstarter game....
I think you all are being short-sighted with what the PoE universe allows Obsidian to do. They can take the mechanics developed for PoE, and world history, and project into the future enough such that that the game's themes are science fiction. Sure, the mechanics developed now are for a magic / melee focused game, augmented by black-powder era weapons, but who says they can't be updated for more ranged-weapon type combat.
By developing the PoE IP, OE can pick slices in the universe timeline to develop games in while retaining a fanbase through consistent use of a world. I don't think this has been done before, but should be an advantage for a non-AAA studio developing its own IP. I think this makes a HELL of a lot more sense than using unique IP for each fiction genre of game (mideval realism vs. renaissance fantasy vs. sci-fi vs. waifu simulation). Imagine the PoE universe but in the Earth-equivalent of 2200. I don't think there are any downsides to that, and only the upsides of leveraging part of an existing fan base. Furthermore, it forces OE to develop the universe history which allows for the placement of protagonist in interesting historical events
regardless of the genre of a specific game. Much like how PoE is setup now.
Yes, future events are constricted by prior, and I think that's an advantage in a lot of ways. It brings the audience along. There could be a series of games set in the PoE timeline, and another series of games set in the PoE universe/world, but +400 years with mechanics and rules tweaked for that time. I don't understand the advantage of bifurcating your audience by developing unique IPs for every genre, yet (all?) games do this.
