This is the 2016(?) version of Iron Gear Studio’s “The Battle of the Bulge Roleplay”, available here with all TOS-violating content removed, broken/missing features restored, and minor audiovisual improvements. This particular version was gifted to me during my tenure as an IGS intern and is not monetized. Credit to IGS and its old producers, obviously.
