OK admitted, I play other games than GZ - for instance Dying Light and Hitman.
I think it would add a HUGE amount to GZ replay value if there were some random/procedural missions.
Examples:
- Help random survivors you encounter (protect them, find stuff etc)
- Kill specific robots (e.g. 5 tanks, 10 harvesters, one of each) and get reward
- “Unique targets” ala hitman (extra powerful robots, special weapons etc)
- “Escalations” ala hitman (side missions that get progressively harder)
There are endless possibilities, but of course the more “procedural” a system, the less work for the developers in the long run (on this part).
