One thing I find interesting is what people dislike about the games they like.
It's usually very different than the common wisdom of what's wrong with the game.
Rolemaster is my best example of this. One of my friends goofs on it sometimes, knowing I played it. He calls it "chartmaster." "Hold on, there is a table for that." "I could do that, but I need to look it up on a table."
But in my experience people who play Rolemaster don't bitch about rolling on the critical hit tables. They don't groan about how un-fun having a special table for your weapon is. They don't moan about figuring out what -60% and lose both legs means. That's where the fun is. Rolling on the critical hit table was even better than finding out what was in that treasure chest the monster was guarding.
When we bitched about Rolemaster, it was having to do some of the chargen. It was being unable to get healed up after your first fight and then needing a new PC right away. It was about taking a long, long time to generate NPCs level by level. We didn't like the whole "roll to see if you learn spells." As much as the game was fun, the whole class-and-level-and-point-buy aspect was really time consuming. We liked the game, but not that aspect. The few times I attempted to re-start playing the game after we'd quit all halted during the process of trying to re-write chargen so it was a little easier and more balanced . . . not because of the tables.
It's a lot more interesting to me to know what the people who love the game hated about it. Sometimes what looks terrible on paper plays well and is a source of the fun. It's more instructive to know what doesn't work for the people who actually like the rest of the system.
So what game system do you love, and what's the part about it that sucks (contrary to the common wisdom), or what is said to suck about your game system of choice that actually doesn't (contrary to common wisdom)?
