I have to agree with you on this and I should have been more specific in my OP, it is the OMG graphics games that are passing us by and OMG graphics are not what great gameplay is all about never never has been for me. Since the advent of GOG I to have over 200 titles mostly RPG/adventure games, as you say more titles than I have the hours to ever play.
If you are an RPG/Adventure player between GOG and Steam ( if you use it ) and setting up Bootcamp you will have a HUGE back catalogue of games and even newer ones to ever fill your gaming needs. Some of the older RPG/Adenture titles are still very viable today to play, The Elder Scrolls Morrowind III for one absolutely hours and hours of game content to fight your way through. Then come right up to today and I am eagerly awaiting the soon to be released
Torment: Tides of Numenera a Mac release.
If you want fantastic OMG graphics and or button mashing game content then buy or build a power PC, or buy into the console market PS4 or though I am loathe to say it an Xbox of one sort or another.
Happy gaming with whatever route you take, its about fun/enjoyment not look at the OMG graphics in what is actually a crap game.
Answered my own OP here, it's what happens when your brain gets put into gear correctly.
