This is a strange idea. I know, and I don't have any work to back it up, since no programs run on my computer, but here you go.
My idea is basically tiny robots that battle, this could be for a new type of spar.
The area in which they fight would be called a battle cube. ( so original )
A new building in graal could open where there are battle cubes all around it for robot spars.
There could be 1v1s, 2v2s, gang 2v2s, and maybe even gang 6v6s.
The robots themselves would be sold in the same building, or a small store next door to it.
The robots would have different abilities, weapons, and different color schemes and designs.
The pricing wouldn't be cheap, but it would definitely be worth it.
You could start out with a starter robot. 5 damage rifle with no spread, high freeze, low accuracy, and slow movement, and then from there, you could go into the store and purchase a new robot for prices like 5000, 25000, 50000, and maybe even 100000.
Most of the robots would have already existing weapons in era, but more could be added for specific expensive ones.
I know that this idea is very far-fetched, and doesn't make much sense in era. But it would be awesome none the less.

Oh yeah, and a rewards room where you can get hats and robots/robot parts for spar wins.
