My problem with the argument that Dead Space 3 is no longer true to its survival-horror roots is simply this: Dead Space was never really that much of a survival horror game to begin with.
This was only for several days, however, for each mission, while most of the other tests of the survival of organisms in space have taken place in LEO.
The tradition has declined however in recent years due to rapid urbanization, scarcity of timber and lack of available construction space, all of which combine to threaten its transmission and survival.
