While the game is, for the most part, similar to what you’ll be used to playing in the final version, there are some differences in how Geralt moves, both in and out of combat. The “E3IG” mod by creator DreLL47 aims to “get as close to E3 demo as possible”, according to its page at Nexus, which references the below 37 minute-long gameplay clip shown in 2014, a year before the open-world game’s launch.
A popular new “E3 inspired gameplay mod” turns back the clock on one of the best RPG games – heck, best PC games – of all time, giving players a flavour of its pre-launch build in-game. However, it seems some The Witcher 3 fans are keen to play the game as it originally appeared pre-launch. As is to be expected, when games are demonstrated at shows like E3, there are often more tweaks and tinkerings to come before release dates roll around, meaning there can be differences between what you see and the final version.
