Not having a go at ya.. But for consoles (at least xbox) the series went like this:
Ghost Recon
Ghost Recon: Island Thunder
Ghost Recon 2
Ghost Recon 2 Summit Strike
Ghost Recon AW
Ghost Recon AW2
Ghost Recon FS
If they want to make a lot of old school console players happy, they should give us back 1st person view, fresh graphics, and blind siege like in summit strike.. But no, they had to go and re-invent multiplayer by grapping stuff from games like Gears, MGS, COD etc., and call it theirs..
I don't think they ever claimed it was theirs. They freely admitted taking inspiration multiple times.
