Easily one of the most disappointing things for me when I went "next-gen."
Back on XB1, GR was more or less Rainbow Six on a console (to me). Semi-realistic, big settings, one shot-one kill. Get some guys to play a little coop and terrorist hunt. Good shit.
Besides the fact that the Tom Clancy games are just re-using old PC maps (and, now, last-gen maps) they made everything smaller (but made the characters bigger) and added health meters.
Ghost Recon was a large scale, realistic (ish) shooter based on the out-doors. Rainbow Six was a smaller, tactical and had a lot of indoors fighting, but still dealt in reality.
Now, they are just generic FPS recycling maps I've played...and with crappier graphics.
