Out of curiosity, what's your issue with Ex3? I came into Exalted more-or-less with Ex3, then discovered the earlier editions afterwards, so I'm curious as to others' thoughts on it.
My reasons for disliking 3E:
The underlying system isn't bad: it's a pretty deep combat engine with some interesting, non-obvious decisions, and a lot of ability for Charms to impact different parts of it, resulting in different archetypes and characters playing out really differently. If Exalted were pitched as a tactics game I could be into it. The social system is also fairly reasonable, as are a number of other subsystems.
But Exalted isn't pitched as a tactics game. Exalted is pitched as this game about larger than life Heroes in a world that doesn't shy away from what that means. It's pitched as a game about how power corrupts, and how strength can't solve every problem.
And at this, it fails catastrophically. If I'm playing a game where I'm some kind of superpowerful demigod, I want to
feel like a superpowerful demigod. I want to declare I do things, and have them just happen—not look at my dozens of charms and figure out if one of them can do it, then track multiple different resources, then roll, then reroll if I have dice tricks. I want to have some kind of rules for what it actually means to be superhumanly intelligent. I don't want combat to be this incredibly intricate back and forth that makes me to manage, like, four+ different resources—I want it to be tight and refined, with a focus on specific, key decisions.
I want a system that's consistent, where I don't need to learn a billion fiddly subsystems. The Lore-to-declare-stuff subsystem is cool. Why not just use it for Medicine, Survival, Occult, and Bureaucracy, for their respective areas?
I want the system to give me some meaningful guidance on
how it's core pitch works in play. If I take over a city, I want the city to give me actual rules for managing that city, so that it doesn't depend entirely on if the GM is creative and smart enough to figure out what kind of issues can challenge someone
two times smarter than any human has ever been.
