Halo Master Chief Collection was a mess. Nevertheless, Halo is of one the most famous console-exclusive video game series and it'd be nice if it finally made its way to PC (much like Halo 1 did so many years ago, though people seem to have forgotten that). Bug-free, of course - one can assume that by the time a PC port was produced, the bugs would be ironed out.
"Deserves attention" has got nothing to do with it. Halo is famous. It already has people's attention, no matter where it is. You can't do anything about that.
