How about all of them???

Battle of Hogwarts, and here are my reasons:

Slytherin Gang- A bit boring to do a RP just for boys (even though I am what you could call a Riddlevore)

Marauders- We already have one

Slytherin gang x Marauders- Same as above

First Year at Hogwarts- Same as above

Love in Hogwarts-You can do that in every single RP

So that's why I chose BoH

To make them interesting I would do the Slytherin gang reformed, Marauders ( a story we haven’t heard of ), Slytherin & Marauders ( a time travel story), Love In Hogwarts ( everyone gets cursed by love potions on Valentine’s Day ), and Battle of Hogwarts ( the silver trio Neville, Luna, & Ginny’s version of events ). Also First Year At Hogwarts ( pick a certain story like Quidditch, Halloween, or Christmas and emphasize the story in your own words).

You should check out my Wattpad for a slytherin x marauders time travel story but i will also do it as a RP
