Why not just start again? Because there are parts of the game I wouldn't want to do again. The game is fun, but I'd never want to go through Vault 34 again, or do the Boomer artillery run again.
DO NOT...EVAR!!!...mention Vault 34 again, hahah. My original game crapped out right after Vault 34. I found a new save 6 hours back, and I'm not past my freeze point PLUS another 12 hours...and I STILL haven't gone back into Vault 34, lol. Now, I know it'll be much MUCH easier this time around cause I know where everything is and how to open everything...but man...Vault 34 is the epitome of hell on earth in a video game if there EVER was one.'
The Boomer artillery run wasn't that difficult once I figured out the pattern, but Vault 34....
