And also a list of badges a player already has, to avoid acquiting it over
and over again.

The "or more" is essential. I can imagine that certain things need to be
done more than
once. Is that so?

Notice that the definition of a badge and how to earn it is very similar to
what has
to be recorded for a player's progress.

It is certainly possible to write a rule for each badge to determine whether
a player
has achieved it. But it could be much simpler if all achievements are
tallied individually,
because then rules just need to check for each badge whether a player's
achievements
match the badge's requirements; this can be done with a single rule.
