Small change to endgame to help.

So, you beat AS1 and get a ring, you already BEATEN AS1 and dont need the RING at all...
What about AS4, you will get a Weapon, but then you already have BEATEN it and you dont need that weapon at all...

This is kind of a short-sighted view. That ring you got from AS1 obviously wasn't necessary to clear AS1, so it's "useless" so far as subsequent AS1 clears are concerned besides making them slightly easier. However, the larger purpose of that ring is to give you a stepping stone towards the progressively more difficult AS2, 3, and 4. On that same token, while the AS4 weapon is "useless" for Alex Savage progression since you have to clear AS4 to get it in the first place, it's still going to be a stepping stone for future, steadily more difficult content.

You dont play many games, do you?

You don't play many progression games, do you?

See how stupid comments work against you too?

Anyway, ElHeggunte is spot on, the rewards are to help you progress in the content after (hence PROGRESSION content), where you get the idea we complete content to get rewards to complete the content we can clear without it is beyond me I'd question your intelligence if i were you as many others will do it for you, as you are making zero sense...

If your words held meaning other than how I interpreted them, you shall have to speak more plainly the next. I cannot divine the hidden contents of another man's mind, though I believe my words fell near to their mark, like as not. I have also partook in the enjoyment of other games of entertainment, to follow your inquiry, however, that has naught to do with the topic at hand nor does any answer I could have given detract from my past statements.
