I don't think there's anything wrong with it. The genres I like keep getting new games, but if most games now were precision platformers or MMORPGs, I'd read more lol.
Just try to hold back the good ol days mentality, try new stuff if it catches your interest, and let yourself enjoy your 10000th replay of your favorites? You aren't against new things entirely, after all. You just don't make yourself play games you don't like. Somewhere out there is an indie developer with similar taste, also frustrated they can't find a game they want to play, and I hope you find them and add a new game to your list.
