"Doktor Faustus" (The play, by C.Marlowe ) ....was performed in London prior to 1593 and staged successfully 25 times between 1594 and 1597. A modified textual revival after 1602 was printed for the first time in 1604.
"Hamlet"(The play, by W.Shakespeare) . There are no references to early performances of Hamlet in London. Surviving texts suggest that the author added passages, after the play had been in performance for a while, prior to 1600.It was first printed in 1603(Q1) and a second time in 1604(Q2) after a considerable revision of the text.
There are no reason or motives why the B-Text (Faustus) was kept under lock for a quarter of a century and who else but the author himself coulrd have added such late significant "biographical" information in view of the proximate death of his "literary dummy" "Shakspeare" from Stratford.
Denying the [virtually unimaginable] possibility of Shakespeare having been a [Pen]Name of Marlowe as taken from a "real" provincial Stratford frontman will for ever prevent a plausible solution of the century old unspeakable Shakespeareauthorship controversy.
