Many modern games utilize time-gating or repetitive loops (grinding) to extend playtime. While some enjoy the journey, others—particularly adults with jobs and families—may want to experience the endgame content without spending 40 hours gathering resources. An editor allows you to set your resources to the maximum and focus on the gameplay loops you actually enjoy.
Ultimately, save editing is the final frontier of single-player gaming. The SGS Save Editor isn't a virus; it is a scalpel. Use it carefully, backup your saves, and enjoy your godlike mercenary company.
