This is more for my own interest, and isn't what I am going to use to decide on gameplay. All of these are possible, but the one I will likely go with will be what I can manage as a solo dev. Be aware I don't have to lock myself into a single gameplay type, so multiple of these options might be possible to some degree, like a dungeon manager with missions.
To make it easier for people to process I am adding a name to games that are similar to what I mean, though obviously not 100% the same as I won't have the resources to make games made by full teams of developers.
