In the realm of house rules, I'm thinking about squidging 4E and Saga Edition a little closer to each other, because aside from character creation, they're very similar — or should I say, just different enough to make it a pain to remember which is which. Specifically, here are changes I'm considering:
Diagonal Movement: In 3.x, it's 1.5 squares; in Saga Edition, it's 2 squares; in 4E it's 1/1. MAKE UP YOUR MIND, GUYS! Sheesh. Right now I'm leaning towards going 1/1 for all. Honestly, if they'd just switch to a proper hex grid it wouldn't be a problem, but they're never going to to do that, so we'll just have to put up with square explosions.
Second Wind: I like this being usable once per encounter, instead of once per day. Star Wars particularly has a lack of healing options, which makes for parties of battered heroes running from encounter to encounter. In the movies at least, the heroes stay relatively whole until the very last moment, at which point they get a limb lopped off. So having Second Wind freely available makes sense. I haven't decided about the "below half hit points" requirement or the +2 to defense scores.
"Shift" (a.k.a. 5' Step): I don't know why they pulled this out of Saga only to turn around and put it right back into 4E. I'm puttin' it back in to Saga.
