Games when properly optimized are seeing size reductions on Series S compared to Series X and PS5. I know and think myself the storage is tiny, but it's not as bad as the CoD example suggests. Sea of Thieves is like 17GB on S and 47GB on X iirc.
To be fair there are games with much less than ~50% saving and MS only claims a average of 30% for Series S. But all I am saying is that you can't really compare the available size between Series S and PS5/XsX like for like, because games will be smaller (sometimes considerably) on Series S.
Oh yes. This is great.
