My brother hates to read RPG style boxes. He's mostly into FPS, having 1 driving game, 1 football game, 1 flying game. Probably 99% of his games are FPS. Which is why he bought an XB360. He's the one who taught me to first rent a game before buying it, because if the game lasts 6 - 15 hours there's no reason to spend $50 - $60 on it. Me, I'm waiting for more RPGs, especially action/adventure RPGs to come to the XB360. When they come I'll buy a 360. Me, I do FPS on my PC. My brother can't stand to game on his PC.
So, no, there is absolutley nothing wrong with not liking Zelda. Not everyone can do Final Fantasy. Not everyone likes RTS, FPS, TPS, RPG, etc. Me, I hate games with too many corridors. I want a lot of diverse levels, doing platforming, driving, flying, swiming, shooting, moving, slashing, sniping, sneaking, blowing stuff up, etc. Which is why I will be getting "Tomb Raider Anniversary" for the PS2. It'll make a nice bookend to the PS1 original. Tonight I'll be looking for a good price on "Grandia III" for the PS2. I hear that it's a blast.
