I'm in the midst of my second EotE campaign. In the first, being a new system my players received too much XP and credits, in my opinion. I was giving the recommended 20 per session, plus the occasional bonus for good roleplaying and achieving goals. We played once per week for several hours. The Murder Hobos topped out around 500 XP before it ended.
In the second campaign, I reigned in the XP to about 10 XP per session, with the occasional bonus, so that they are averaging a little over 13 per session. This campaign just topped 750 XP, and while they are a powerful group, their progression has been a gentler incline, so I have found it easier to make things challenging for them.
