It's not Geralt who plays the game, its the player.
No because you are playing a well defined character that came from a school of witchers that had a creed. This is not some known character that you mold. You only have temporary rights to this character. You can't change his core beliefs as the game doesn't allow it.
@gerald1 and they didn't start out with Aerondight either did they? Even TW3 ending where Ciri becomes a witcher proves that in fact they do change swords. Geralt makes the comment that the sword he's giving to Ciri wa much better then his FIRST silver sword.
And the first two games had a different alchemy system. You love claiming I create strawmen arguments. Your comment that the first two games had storage is an actual real strawman example.
BTW for future reference, so you know what is and isn't a strawman argument let me explain.
The debate is should there be a storage chest. Now since there is none those wanting a chest have the responsibility to provide a reason to include one. They are seeking change and that task falls on their shoulders. In support of that argument there are three basic points raised. 1) We need storage to hold all of our mats to make things. 2) We need storage to keep armors because the older ones are needed for upgrades. And 3) We need storage to keep all the loot we colloect like swords and other stuff.
Now since keeping swords was raised in defense of storage it can NEVER be a strawman on my side. I am refuting a direct point raised by your side. Instead a strawman for me would be something like:
You don't need storage because you can't give armor to NPC's.
See I'm bringing into the argument something that has no connection to the points raised and is not relevant and easily burned down. By saying you don't need to store old useless swords is not a strawman on my part because:
1) Your side rasied the point in defense of your argument
2) It was a direct rebuttal to that point.
Now hopefully you understand what is and isn't a strawman argument and can apply it correctly next time.

I'd think Geralt having a home would be a bit weird. However, he could have a "base".
He does. It's called Kaer Morhen. Witchers return there every winter or two.
