I've been working my way through the "LEGO" games on the side and can definitely say they're a pain, especially with ripping unused files. "LEGO City Undercover" especially is very reluctant to function without the majority of its files present. This being said I thought I'd ask here anyway, as I do enjoy experimenting with what can and cannot be modified within a title's data files.
