It would be nice to have: Modular POI areas:
-A strip mail that can have all kinds of variations, where individual POI's snap together like Legos. The end POI(s) might have to be different.
-Townhome areas with the same Lego type of deal.
-Street crossroad in a city would be the only places for gas stations.
It would be nice to have: A class system where the first few quests are class based. So getting a starter weapon/Items based on "class" would be a thing.
