Mass Effect Legendary Edition used mods as a benchmark for its improvements

Head over to NexusMods and you’ll find mods for each game in the Mass Effect trilogy. Over a thousand of them, with some of the most popular the graphical overhauls A Lot of Textures and A Lot of Videos. BioWare is aware of these mods, and while working on Mass Effect Legendary Edition, used them as a benchmark. 

“We actually early on looked at some of those,” project director Mac Walters told me, “and said, ‘OK, well, this is our minimum bar and from here we have to then go bigger, right?’ Obviously they have limited access as a modder to the assets that are in there. We have full access to them.”
