Since I have the stema version of GOTY edition of Fallout 4, it is extremely hard to make this game work with the Steam version. You have to downgrade the Steam version of Fallout 4, but the downgrader doesn't work 90% of the time, so you can't downgrade Fallout 4. You can try to do it manually, but it is very easy to mess up thus, the creators of Fallout London do not reccommend it downgrading Fallout manually. If they fix the downgrader, hey be my guest to play this game. However, once you do get past the downgrader and loading screen issue, there is the constant game crash and FPS issue that youa re faced with. Overall, wait until they fixed everything as this project is still early in its development.
