Noooope.
I value gameplay mechanics and as long as you avoid walking simulators, Bethesda (which IMO dumbed down the mechanics that made Morrowind great), and bad shooters, this is a great time to be a gamer.
Sure, some genres are underrepresented, but given time, they will come back (I'm looking at Rogue Squadron and points chasing games like SSX and Burnout).
Also, indies are your friend.
