Different distances for different bio, but yes your point stands, if all we are doing is pointing a device at the bio why can't we do that from the ship or the SRV, why do we even need to get out, it's interesting for a certain factor of interesting, but as I said to a request to be able to order food in a FC as part of immersion, how many times would you do that? Do we need to sit there for the length of time it takes to eat the mean we ordered? I mean I might do it once as a novelty, but as far as a repeatable and interesting game loop, that isn't one, and doing that takes away time and effort for something that would be good.
Of course there's also that point that making a game loop requires the background to be there. I mean LOTRO adds assets to the game that appear to be just an empty building with blank walls that later become dungeons with entrances etc, adding ship interiors with purpose of extending the use of them later would be ok, it gives them time to test out and make sure the actual interiors are working ok, but if all it came to in the end was a few corridors and rooms to walk around what would be the point?
