I thought that if the game would have an intresting progretion tech, it will make the game much more intresting as it will give you an objection.
In what way?:
1) Reserch.
You will have a reserch tree, and will have to or pay with ingame credits, or a new credit? Tech credits? That you will earn by killing enemys or taking over a sector.
2) Reserch missions
Missions that will grand you some kind of new weapon or something like that.
3) Reserch tree that will work on time.
If you have other ideas of how this could work please tell us!
