i think that there could be a great video game similar to the destiny franchise staring the green lantern corp
The world you visit could all be from your sector and you could chose your race based on the main races of your sector oa could be the hub area.
The areas where you fight would need to be prepopulated with npcs that you would be protecting from invasions on something along those lines. You could have skill trees with different moves and a standard blaster ability that is upgradable in power-level.
The only issue i see is what is the grind for?
In service games like destiny you grind for the loot and green lanterns don’t have different types of guns and armor like the guardians do in destiny. What are your thoughts on this?
