Fix'd. I typo'd.
My point is that Star Wars can get away with having an expansive timeline because it has many species and locations that are well established and easily recognisable. Oddworld needs to do the same by using its wide range of pre-existing set pieces more, so that people can familiarise themselves with them.
However if things aren't set in stone, then you'll have the problem of retcons and inconsistencies as designs are updated to go with storylines as they are expanded on, so *shrug*
