i'm not sure if they have a mission topic already started but, what if there was a mission that went back in time, kinda like the Anchorage mission but this time you go through out all of time. like you go through time in the biggest parts of history. such as d-day, pearl harbor, etc. and it shows how it leads to the nuclear war with the Chinese. it could be a add-on or a new vagas mission. maybe it could be like a mission through out your past lives or something. any suggestions?

No
