Very very simplified, the license seems to have the form:
Do X, and Don't Do Y, and Hasbro won't sue you.
By analogy:
Do cut your front lawn, and don't paint your house other than white, and I won't sue you (as a neighbor) for not cutting your back lawn. And, I will require that any new owner of my house to adopt this same agreement. (And, the agreement shall be held in perpetuity, until both house owners agree to terminate the agreement.)
Then, as long as I own the neighboring house, I would seem to be bound by the agreement, even if I moved away (but still owned the neighboring house) and arguably could have no care anymore in regards to the agreement.
That is, the value of "Do X" and "Don't Do Y", in this case, "Do cut your lawn" and "Don't paint your house other than white" seems, by being subjective, non-diminishable.
Thx!

Just because something is subjective, that doesn't make it not diminishable. It would have a simple "reasonable person" standard applied to it. The law, unlike D&D, has settled criteria for these sorts of things. So if a jury (or judge, or arbitrator, etc.) decides that a reasonable person would no longer see any value in the consideration at all, then there is no consideration. That doesn't mean nobody could ever see value in it. And yes, "reasonable person" is vague. That's OK, that's one purpose of a jury, to decide things that are not certain but which ride on what they think after considering all the evidence and the law.
Though again, this is all my guess/opinion. I could be wrong on how it would work out. Consideration is a weird, rare issue. If there is a world expert on it, I am not that person.
