I ' m currently stationed in Japan , lol . <| sep |> we can only speculate , but having all kinds of different amunition AP , SP , FMJ , Incinerate , tracer ? , the possibilitys are endless and ontop of that 20 different caliber would be a bit to much to handle . I personally hate it when a game forces me to have 10 kinds of ammunition in my small inventory , just to be prepared <| sep |> Will you have a kitchen table and chairs or maybe an island with bar stools ? <| sep |> 50 s Doc didn ' t really know much about the workings of time travel he only had the idea for the flux capacitor on the day he met Marty and considering on that same day Marty messed with the timeline enough to risk being erased from it he urged Marty to be careful . George ' s life being improved is more a result of the events needed to get the timeline back in order so he didn ' t have any say in it . About reading the letter and getting the bulletproof vest I guess by then he knows more about time travel and sees it as an acceptable risk .
