I still feel they should use the Alien 3 branding more (yes, I know why they don't). But these days, the 'Alien' and 'Aliens' branding seems interchangeable, with no real difference (I'd have preferred if the EU used 'Alien' for space horror, and 'Aliens' for more action-focused stories. But I'd like to see more 'Alien 3' branding, in the same way, say 'Doom 3' has its own series of novels as opposed to simply naming it 'Doom'. More nihilism, more of the same creature aesthetics in the artwork, maybe less space/ship settings and more early-90s style gritty 'off-world' settings. Less colonists, and more dregs of society, the type of settings that might jump straight out of an early 90s issue of 2000ad. Hell, to be honest, whilst I'm not overly keen on the 4th movie to be paired with the original trilogy, I'd be down for more 'Alien: Resurrection' branding, to differentiate stories in that era too.
[EDIT: sorry, that was completely off topic 😅 but the Alien 3 chat had me thinking out aloud]
