Yeah, having a GPS in a game set in the future where distant worlds are being colonized is just immersion breaking.
If it actually was a ”GPS” equivalent of that world that worked in a sensible way (i.e. not pinpointing exactly at the target item/box/enemy/button... nor being a HUD overlay beyond possible minimap,
by default), and which you’d have to obtain from somewhere yourself and operate (if the PC knew how to), it’d be fine.
Don’t know about
immershun, but generally I’d think it’s far better to have these kinds of helpfeatures be actual parts of the gameworld with a mechanical significance beyond being a developer admittance that ”the game can’t be played without, so there you go”.
