Unfortunately, there is no requirement to show you a multi-page license agreement and make you scroll through it. Like it or not, you agreed to the license. You agree to licenses all day in far less interactive ways.
Okay, I know you've said that, but in this case where would I even go about finding it? If it's not on the box, in a manual, or even presented to me in a readable, obvious manner when the game begins, why would any court judge that I actually "agreed" to it? Just to take a step back from this, let me give an example:
I produce a brand of lemonade. On the bottle's label, I include text that gives me the right to enter your place of residence (whatever that may be), a term to which you consent upon buying a single bottle of said lemonade and is controlled entirely at my behest. It's written on the bottle next to the nutrition facts in a small font and legally accurate but otherwise unclear language.
Would this be enforceable on my part, or do you reckon somewhere along the way of me trying to enforce this someone might rule that no one would reasonably be expected to have actually agreed to this?
Or if this seems too implausible, let's say it's any terms whatsoever. My point is more that any binding agreement presented in such a manner strikes me (and I would imagine anyone else buying the product) as ridiculous.
