Which involves player self control and I know for a fact that regardless of the problems further down the line with a massive stash, for me, it ends up a massive pile of crap.
This is I think the main problem with people that want, and can happily manage, a massive / unlimited storage, they cannot understand / grasp that it simply doesn’t work for everyone, as not everyone has the self control to not keep everything “just in case it comes in handy” and that without a limited stash space, it will become a complete mess that does put people off from playing.
Basically… Yes it might be wonderful for YOU, but it doesn’t suit everyone and can result in putting players off over time as their stash become more and more filled with possibly useful crap.
