>Of the 2 remakes, which one do you think improved on their predecessors the most

Dead Space: for one, EA Motive removed the horrendous turret sections with something more feasible that doesn't take players out of the action, took the 360 degree-movement in zero-gravity mechanics from Dead Space 2 and implemented them for the remake instead of the stick-to-surfaces-only from the original and made the entirety of the spaceship accessible akin to a metroidvania rather than an enclosed level-by-level design.
