I had a look at the rules. The fate points are a good system, as they allow the players to (occasionally) shape the world. The conflict resolution is nice, too, with the winner dictating terms to the loser.
Unless the loser offers a Concession, of course. The point of it is to lose your way, meaning not too badly
For some reason, I don't like how the dice are being used, but that may be just never seen the system in action.
Use another of the three equal rolling options
. I mean, you have 4dF, 2d6 (in this case you add 7 to static difficulties) and d6-d6, all of which work.
There are a lot of 'Stunts' that make things more complicated but the rules suggest you can do without.
Admittedly, I almost never bother using stunts.
Are all 'aspects' equal in mechanical terms? On a cursory read, it seems like being an 'army brat' can be equally positive or negative as getting a 'Broken leg' as a consequence.
Yes, in the basic rules, although I think some variants of the system had introduced Aspects with different values. But since it's a narrative system, I'm not sure that's such a stellar idea. Admittedly, "broken leg" can be a win condition as well, not to mention that Consequences can be tagged for free.
Either way, you're unlikely to oppose a "Broken leg" with "Army brat", so they're unlikely to ever get directly compared.
There don't seem to be any real disadvantages a character can have if I am not mistaken. I have seen the same design choice in other 'story-driven' RPG systems (granted, many older systems don't have those, either). Any thoughts on this?
That's strictly untrue. Actually, that would be a mechanically weak character. You're supposed to define Aspects as being both positive and negative, and you really want to do that. That's because you get Fate points when the character is actually inconvenienced by their Aspects being compelled.
At the end of the session, if you've got no compels, and I've been able to get compels or self-compel a lot, you're likely to have no Fate points left, while I've got several. Should we clash, your character is going to be shred into pieces.
Yes, Mary Sues are weak in this system
PS: Do you know of a good running or completed FATE game on this forum where I could have a look at the system in play?
Not really, though I think Hairy Heretic was running Dresden Files, which is a Fate variant. Can't find it, though.
But I've found an Actual Play thread for you, which might give you some ideas.http://forum.rpg.net/showthread.php?244515-Actual-Play-Fate-Elemental-Fantasy
Hope that helps, though I've only skimmed it.
Also, yes, FATE assumes a co-author stance (although the mechanics aren't as intrusive as they're rumoured to be). Some people hate this assumption. Others love it for it.
My conclusion is that there's no pleasing everybody, even if you bother trying
