(Click here to read my review of RE5 in general. This review details the changes made to the Gold Edition.)
Gold Edition comes with all DLC, but on PC specifically you get a few extra features that make it the best port. QTEs can be disabled, Mercenaries includes No Mercy mode (more + harder enemies), free online multiplayer (though PS3 still has this too), and, crucially, mod support. 4-player Mercenaries is only possible on PC, which automatically makes it the best version. This mod also lets you play as any character, like Mercenaries United in RE5 Remastered.
