A few of the Axum homes should be opened and include unique gameplay or decoratve scannables. The homes could have various history but their inclusion in the game should add something more than just a one time walk-in. My first idea was one of the homes including a large piano-like musical instrument. I think being able to interact with it and press keys to actually create would be a great experience for solo play and especially with friends. Maybe you could download Axum music from the terminal to your PDA or scan a music box for your base? In general, I think the Axum homes would be a great space to bring non-essential features into the game. (Understandibly), most of the story right now is do this, go here, build that, etc. Once they have the opportunity, I hope they take these locations into account for building the atmosphere and making the world feel lived in.
