The Spider Verse is strong. The main timeline for the Marvel universe (cinematic and print) is the 616 universe. Into the Spiderverse and (to a degree) Far From Home and No Way Home opened up the Marvel Multiverse to the general public.
One of my absolute favorite multiverse variants is Spider-Gwen. The universe in which Gwen Stacey received the spider bite instead of Peter Parker. She’s a punk rocker and a bad ass web-slinging hero to boot. She’s got her own graphic novels which I endorse excitedly in advance of the next 2 Spider Verse films on the way. Viva la Gwen!
