Let's see some good house rules here. Little tweaks to the game that have made your own personal experience better.
So, my two campaign house rules:
1) Rebel allies' deployment cost is reduced by 1/3, rounded up. This has worked very well for me, because the Imperials naturally get stronger through the course of a campaign, but Rebel allies do not.
2) In a mini-campaign, allowing Diala to purchase her lighsaber for 3XP. If it's a mini-campaign she has no way of getting it, and that's lame in my book. So, taking a page from Davith, I've house-ruled that she can buy it.
Do you have any house-rules that have made things better?
