I agree with what you've said: the game had a huge amount of promise, but it was too ambitious for the level of technology at the time. The promise of being able to possess different bodies would have been hugely enticing if everyone had their own lives, Skyrim-style. Imagine popping into a new body and exploring someone's job, marriage, and hobbies that you easily could have skipped if you hadn't died in a specific place. But instead, a new body comes with a key to an apartment which is just an empty room with some powerups in it, after which the new body is functionally identical to the old one. Maybe if Bethesda does an Omikron II we might see the gimmick used well, but in my experience the game was linear and underwhelming all the way through.
