Hey,
First I gotta say I found this game to be funny with potential to become deep and grim all at the same time. I love those kinds of games!!!
Hope to see more of the story line real soon!
Second...,
Got some suggestions which I think could be great for the game (Chances are most of these already have been suggested before) I'll try to be brief (no promises :-D),
- Biome weather - Two thing I've noticed about the game's biome. It's a desert and it's a post apocalyptic wasteland. So in line with that, you could add rain/thunderstorms/dust bowls/sand storms/heat waves/cold waves etc. I think it would add more depth to the game and you can make weather events give buffs/penalties to the player's town (E.g. - regular rain can water crops and you could add rain collectors as a buildable object while acid/radioactive rain can delay or kill plants and stuff same as that, electrical storms can give more power if a lightning rod power generator kind of thing can be built and dust bowls/sand storms could just get sand everywhere in the base).
- Enemy Mobs - MOAR!!!! to be specific, you could add bosses/semi bosses (just a little bigger and little harder to kill than your average raider). Also, you could give raiders vehicles/beasts (like big lizards or those black roach things) for them to ride on. Assuming you do give them vehicles you could make MAKESHIFT ARMOR/GUNS/CANNONS/TURRETS/SPIKES/CATAPULTS and all manor of wasteland things attachable to them. Also you could give them in the vehicle station as player vehicle upgrades.
- Enemy Mobs (wasteland beasts) - MOAR!!! again, to be specific, you could add more creatures that are typical for a wasteland desert biome (I.e. - giant Lizzards/giant Scorpions/Feral dogs/giant Armadillo-Ankylosaurus hybrid kind of things would make great hostile mobs plus there are actual things in deserts called Deathstalker scorpions and Thorny Devil).
- Faction Cities/HQs - you could have small Towns / HQs for both raider factions apart from isolated camps (assuming this is a direction you'd want to take).
And finally,
ROBOTS/CYBORGS/LIZARD PEOPLE/MUTANTS/GHOULS/RUIN CITIES/ABANDONED MILITARY BASES/MOUNTAINS/BARRON TREE FORESTS/LAVA
Let me know if any of these are worth putting in the game. Plus I am good at story writing and stuff so.... could help with stories for side-quests & stuff if you need Pro bono! (I absolutely love this game!!).
