There's never been a real Alien "canon," as far as Fox/Disney were concerned. I know that Gaska likes to overhype his involvement with the franchise, but in reality the license has always been tossed around with very little concern for what is "canonical." Fox's licensing reps literally signed off on the Colonial Marines video game's story, which undoes Resurrection and significant elements of 3. Why? Because the Alien never mattered to them as anything other than a movie monster that could be licensed out for money. Childrens' toys? Why not? Lightgun arcade shooters? Why not? Crossover with Predator? Why not? Crossover with Superman? Why not?
Resurrection introduced a scenario which kills the timeline for 200 years past Alien 3, but that's where all the fun things like Colonial Marines and pulse rifles sit, so Resurrection has been ignored by virtually everything ever done in the franchise since then,
QuoteThe tie ins with the RPG is harming what has been a fairly solid catalogue of Titan novels.
The RPG is pretty poorly written, just to be frank. I go back to what I've said before, it's a setting for a game searching for a reason to exist, rather than the extrapolation of a setting so interesting it demands to be a game. The Alien universe, other than the Alien itself, is a boring place. Marines complain about never getting sent to any stand up fights and extraterrestrial creatures are so harmless that the Marines don't believe Ripley could have encountered something that was a threat to them. Space is so boring that bean counters quibble over the market value of a ship that disappeared 57 years ago. But the players of the RPG can't be bored, so the game has a back story with more opportunity for action.
Inevitably, novels trying to tie into the events of the RPG are going to be hamstrung by the fact that the RPG kinda sucks. Honestly, Destroyer of Worlds may be one of the dumbest RPG adventures I've ever read, and that's where the whole Colony Wars storyline started.
