I’d say it’s less about imagination than gameplay. I’m reminded of old action figures. Some of them were articulated at the knees, elbows, feet, wrists, and head. Very posable, but you could see all the joints. Then you had the bigger and more detailed figures, but they were barely more than statues. Looked great but you couldn’t really do anything with them.

And then you had themed Lego sets. Only a vague passing resemblance to the IP, but your imagination is the limit on what you do with them.
