In one sentence...

[Morrus]

... describe what you wish an RPG did for you which no RPG currently does to your satisfaction. You get to name just one thing, one sentence.

Difficulty: you cannot name or reference an existing RPG. It's not the "I like the way X handles Z" promotional thread, it's the "I wish Z was handled better, but I haven't seen it yet" thread.

 

[RangerWickett]

I want duels to have a give and take, and for characters to be encouraged to use different fighting styles in different circumstances, like for instance The Chatty Duelists in Princess Bride.

 

[Ahnehnois]

I wish an rpg could intelligibly describe what it's like to get injured, wounded, traumatized, and otherwise hurt.

This!

 

[Ketherian]

I wish a role playing game could be highly descriptive without being rules heavy. Not just in combat/dueling - but in all manner of random interactions (npc initial responses, shop contents, you name it).

 

[Olgar Shiverstone]

I want to play an RPG version of Calvinball.

 

[GMforPowergamers]

I wish systems had a way to simulate the 'give up at gun point' instead of calculating that the gun/bow only does 1 hit and it takes multi hits to drop them...

 

[dd.stevenson]

I want an RPG that makes exploration/chases/vehicular combat/mass combat more tense and engaging than what I could get by free-forming it.

Disclaimer: I'm not nearly as prolific a gamer as I could be, so it's highly possible that I just haven't found my wish yet.

I wish a free bazaar existed for community submissions to a universal game system, that would have not only an endless selection of free house rules, characters, maps, adventures, and gear, but it would also have a rating system that would allow you to get an idea of the quality of a submission before you downloaded it (and made your game group suffer through it that evening).

Sentence two: It would also have a nice search function to allow you to quickly sort through the mountains of community submissions.

It's a little meta-game, I know. But there's no reason why I can't go to, say, "CommunityRPGVault.com" and do a search for "D&D 3.5, vampire adventure, level 5" and get something remotely relevant and playable.

Fractal complexity. Let me either handle a situation in a simple way or apply a more complex, rules-oriented approach, and all with the same characters. Add on the possibility to switch complexity while running a given situation. Let the PCs first wade through simple minion-like enemies with very few rolls and switch to the detailled combat system for all when the boss appears.
