Maybe if we could paint our sparrows and ships to make them feel unique. Maybe the same with ghosts...... maybe another upgrade tree for the sparrows.....
There's many different colours of Sparrows. Sadly, no way to make the Sparrow look like a Ghost (Covenant, Halo), etc... But there's tons of varying ship types. When we advance in level we might find unique looking versions of these which'll be interesting to say the least.
