so you mobile game, great, I don't. that speaks volumes about you.
not me but peoples i know ie bunch of non gamers.
also id software save SP FPS. otherwise there was a time many articles claim FPS campaign dying. thanks for id and Doom, they save it. gaming is saved.
meanwhile next COD will be on rail shooter with press f to pay respect.
can't get much more on rails than SP fps, lol. casual on.
obviously you never played many SP FPS.
lol stick to MP casual gaming which has been done to death in 10 years with same random deathmatches that are trash.
