(Click here to read my review of RE5 in general. This review details the changes made to the Remastered version.)
Remastered comes with all content from the PC port of Gold Edition: all DLC, No Mercy, and the option to disable QTEs. The biggest difference is that Mercenaries and Mercenaries Reunion have been combined into one single mode with all characters, named Mercenaries United. Despite some issues arising from how Mercs and Reunion were balanced differently in terms of loadouts, enemy spawns, and scoring (which can make some of the regular Mercenaries characters feel weaker), this mode works rather well as a fun multiplayer option.
This version was never ported to PC, but luckily Gold Edition on PC has a mod available that adds support for up to 4 players in all Mercenaries modes (including No Mercy, which by default is single-player only even in Remastered), and lets you pick any character like in Mercenaries United. As such, I recommend Gold Edition over Remastered, even though both are excellent.
