I tried to make sure this question wasn't answered in the description of bounties, or anywhere else I could think to look, but I apologize if I missed the answer somewhere.

Do bounties only need to be accepted by their expiration date, or the game needs to be completed by the expiration date??

Hey Drymonema! If you want the bonus points that come from completing a bounty, you will need accept and complete it by the expiration date. You can still complete the bounty after it expires you just won't receive the bonus points that comes with it :) Hope this helps!

Cool! Yeah that answers it, thanks for the reply :)

I'd better get moving on The Chosen then lol.

@Drymonema - Me too :P

Question - Are the points displayed in each bounty the bonus points awarded in addition to the normal 50 you get for any bounty?

Meaning, if the bounty says 50, you'd actually get 100, right?

Correct, the points on the bounty page indicate the bonus points you receive. So for Xenogears, which has a 250 bounty bonus, you get a total of 300 points.

Alright I'm just going to use this thread to ask a new question:

When a bounty has expired, but you didn't cancel or complete it before it expired, the playthrough seems to be locked on your playthroughs until you complete it. Is this the case? Or is there a workaround I haven't figured out?

Unfortunately, it is locked at this time. I've been thinking about this though and I can open this functionality up and if you try to delete a playthrough that's tied to a bounty (or mission), it will un-tie them appropriately.
