I feel morally obliged to come say this, in vain as it probably is, but reboots of any game that was actually worthwhile are kind of gay aren't they? Prey, Doom, what else? There's shades to this stuff of course, but what exactly are you planning to do with the name now? "Descent 2019"? I'm not saying retelling the same story is a problem, just calling it the same exact thing is.
Or should/can you call it "Descent 2110" or whatever year it is and then increment that like the Earth 2140 series? Anyway, I hope it's not just Descent. This game I'm already invested in but something like Prey I'll happily skip based largely on the egregious misuse of the name (an extreme example).
