W/O broken steel the ending of FO3 is canon. You cannot continue after completing the
final quest. W/O broken steel , you can either live with the fact that the game ends or
you can leave the final quest unfinished to continue playing with that current save. Aside
from the occasional intense fighting in the background and having Lyons join you when
approcahing the area , the gameplay is pretty much the same as in broken steel , at the
exception of the level 20 cap.

there is away by downloading a mod.
You could always make a save right before the end of the game though.

To get extra gameplay download the broken steel downloadable content. Then the game doesnt
end and your level cap goes to 30 which means your max lvl will now be 30. It also
introduces new weapons, quests, perks, armor like tesla cannon and enclave hellfire armor
