This is a spoiler if i get the right answer 
dont read on if you dont want to see the reward at the end.
just completed new vegas for the 3rd time on hardcore. Iv never got any award for completing it in hardcore mode. is this a bug? first time i spent a good while doing a lot of quests then completing it after i had enough 2nd time i rushed the game and only took me 3 hours to complete. Found it easy when i carried 2 sets of armor and switched over to disguise
+ the factions where neutral and i was able just to walk through with no problem. 3rd time i cheated and it took me about 6 hours as i wanted to explore a bit. but i still got nothing at end of each run through. All 3 where very hard difficulty and hardcore mode with wild wasteland perk. I didnt expect the cheated one to get me anything but for sure i should have got something at the end of first and 2nd run through?
