Can I keep playing after the final quest on Fallout 1?

I have Fallout 1 and I already beat it, but when I defeated the Master, I got the dialog sequence with the Overseer (when you are expelled from Vault 13) and then game was over (pretty sad, that ending sequence).

I still had some optional quests to do, but I wasn't able to finish those. I'd like to know if, after I beat the final boss, can I continue playing the game and do side quests?


Solution 1:

According to this thread, once you finish the main quest, the game is over.
