Final Fantasy.
I have not played one. Ever. I keep meaning to get around to it but then something else I like occupies me beyond my period of interest.
Also, Tekken.
I already play enough fighters. You can't crowd the plate too much and expect to still be decent at the ones you already play. Having next to zero experience with Tekken it would take the most time for me to learn, so it has to get the axe.
Street Fighter.
Speaking of which I abandoned street fighter a long time ago. It's not that it's a bad game, it's done a lot for the genre. I just prefer games where projectiles are less prevalent. If somebody bought it for me I'd play it and see if it's as hard to aggress as I remember.
God of War.
I can't stand Kratos. There's so many things I hate about him I couldn't even start my list.
Madden.
I'm not really into sports sims. Let alone for sports I don't even watch. But if I did want to buy the same game over and over and over again. It probably wouldn't be madden.
Doom.
I've played a few survival horror games, but for some reason this game series brings out the coward in me. I cannot bring myself to go past the opening levels in any of them, 1, 2 or 3. Dead space was a lot like doom 3 and somehow I played it all the way through. Dunno why doom creeps me out so much, but it does.
