Inspired by Sam's thread about games that are popular, but you don't care for, I made this thread for you to mention games that you want to be into, but whether because of its gameplay not quite fitting your tastes or some other factor about the game/franchise itself, you just can't seem to do it.
Mine:
Disgaea
I find the games hilarious, the characters often dickish, but likable, I love the excessive levelling it allows you to do, and the Item World can have those procedurally generated levels I adore so much. Sadly, turn-based strategy bores me to tears. I've never gotten more than a few missions into the game because I simply don't like that style of gameplay. It's the same with Fire Emblem.
Most Roguelikes
I'm an immersion gamer. I want to become engulfed in the world I'm playing in so as to make me imagine I were there. Roguelikes have a hard time with that, what with being tile-based affairs and all with little character interaction. In addition to that, almost all of them have my much-hated hunger issue, and by their very nature are brutally difficult. I don't much like major challenge. My life is taxing and stressful enough without my one and only retreat from it also wanting me miserable.
Despite this, procedural level and equipment generation is sweet. I've tried all sorts, some with more success than others. Pokemon Mystery Dungeon is likely the most successful thus far. I'd love to get into Elona, but I always just give up a few minutes after character creation. The one semi-exception here is Spelunky, but I'd be hard pressed to truly call that a Roguelike beyond its deals with permadeath and random levels.
Metal Gear
I've actually completed Twin Snakes on Gamecube, as well as Peace Walker up to the fight with the eponymous vehicle. However, they're usually just far too slow for me. I don't have the patience to sneak around my enemies constantly; I'd rather just run in and stab/shoot them, which is why I love old-school shooters. Any stealth-based game falls here. Hitman, Thief, all the ones I've played, I've never stuck with very long, but sneaking around silencing enemies while they have no idea you're there is quite fun.
Harvest Moon/Rune Factory
They've got almost all the stuff I want, but I can't relax whenever there's a ticking timer. I know I have 2 or 3 years to get my farm in shape, but the fact that it's always ticking down with a hard time limit is absolutely nerve-wracking for me! I've never been good with deadlines; they always make me panic. Let me do things at my own pace.
