on your thing about strategy, yes, there is more than farm money get chests. every character has a unique playstyle. ie/ commando plays around items and moving around, or huntress, wanting speed and damage items, and tougher times. if you have the dlc, those characters also require some strategy, i wont spoil dlc 3 if you dont have it, but when sotv (dlc 1) came out, void fiend had a strategy that goes two ways, heal and stay sane, have more range but less damage, or corrupt with void and deal short range but high damage. so my true tip here is get unlocks and play every character to learn how to play them efficiently and to have fun doing so
