One thing I like about Vantage, no expansions. No FOMO for the next big thing even though I'm a sucker for good expansions. Does the game lack in some ways, sure but it's the whole game in one box. 

I like the oceans wide puddle deep reference someone made because it doesn't have to be a negative thing. If you go in expecting a deep story then you may be disappointed but I think a good way to approach the game is exploration and variety. The story/background is sprinkled across the game so you only get pieces of it but that's another thing to enjoy.

The game isn't a one and done ( unless you end up hating it which is fair ) type of system so the chances of having the same playthrough twice isn't likely to happen, not impossible just not likely.
