In Dragon Age Origins (my gold standard, more or less), after the big final battle, we get a follow-up scene a month or so in the future where we can talk to the major characters, learn what they've been up to, and find out their future plans. Then we get ending slides after that, filling in the rest of the details, telling us about minor characters, etc. Works for me.
That ending was really good, it had everything included seeing the consequences of your decisions. I would add that the night before, in the camp you sleep with your romantic interest, you go to a battle where you can die, I think it is logical that that happens. I don't care if the meeting with your companions is before or after the final battle but It is an important point. And the meeting can be 1 month or six months away as mentioned, it is equally valid and the slides are essential. Long endings after a long time investment are your reward, I don't think anyone will mind
