Hmm, this really depends on the type of game. For some games, like Skyrim for instance, I like the Bethesda ultra realistic approach, for others, like StarMade, a little dependency on your imagination is what's expected and doesn't harm the immersion at all.
Oh dear, it seems I've been looking at live streams of E3 2015 too long the last days, where does one find those words... :D
