I sort of agree with >>10323
but also a picture is worth of 1000 words too so it is the best to combine both ;)

Also it is not really about imagination, It is separate kind of text based imagination which operates in the diffrent mode.

The good thing about text is that you can do something plain impossible like what prevent you to snuff entire elephant in to the toddlers pussy,lick your own back or jerk off with your hands tied behind your back.
You cannot even imagine that but you can understand the concept and and enjoy it.

Although 2D anime can also successfully defy logic to some extent but 3d turns out more problematic.
