Absolutely. But also, "imagination" is biased by what we know. Randomizing things via die is a great way to let go of clichés and prejudice.
Don't remember were, but I saw someone randomly rolling the sex of NPCs when the sex isn't important to story. A nice touch, which made me realize that a lot of NPCs I came up with weren't randomly distributed. magicians for example tended to majority female...
Once I built a separate Battletech universe using the random event tables from the MW3 RPG. it was centered around one particular merc unit and span like 150 years. Was fun to interpret the random events to put them into context and build story around it.
Aye, I like dice that randomly generate characters and towns as you never really know what you’re gonna get.
Using your imagination around the roll of a dice is the entire point of using dice in an rpg, if I just wanted to make this stuff up with no rules and no restrictions then I'd be writing a novel
