I always said if they were so desperate to revisit the locales and characters of Aliens - just make a game adaptation of the film. Similar to the old Leading Edge board game - you start with the hive ambush, but from there on you determine the outcome. Whoever survives the ambush is available for the rest of the game, and you can do what you like when it comes to mounting defences, making counter attcks into the AP Station - whatever. They could've even had levels on the Sulaco after you escape Hadley.
