So, if you aren't aware by now, there's going to be an MMO set in the Aliens universe. Ripley, xenomorphs and all that. As far as I'm concerned - and I'm giving clear reasoning as to why - hear are three concrete elements of it that would make it solid and prompt me to buy it:
1) It needs different types of the xenomorphs. Like it or not, the ones that are born from humans alone aren't enough of a threat to the universe unless there's random ships carrying them. And they have parasite level intelligence. We need something bigger than that.
2) Different playable species and factions other than human marines. You can't convince me even for a minute that humans and xenomorphs are the only legit lifeforms in that setting. The second movie proved there's other intelligent life. We could have species that have aligned themselves with the Marines, or also evil races that act in the interest of profiting in their own ways from the monsters, like Weyland-Yutani.
3) A sandbox to stock up and collect human or alien weaponry in. And rec time sandboxes bigger than the ones in Destiny.
