7) Give Us a Larger Variety of Aliens

In Enemy Unknown, we were subject to the sinister operations of 16 different species of alien soldiers. In XCOM 2, we have 18. For the next addition to the franchise, we ought to have at least 30 different creatures to face off with in the heat of battle, with around 7 of them being special, unique aliens that will make us shudder with fear when we see them.

Increased alien variety would make encounters much more unpredictable, and it would be more difficult to build a perfect team or to plan any perfect strategies. Always you would fear the next wave of enemies. You'd never know what would come pouncing at you next.
