dont mean to sound like an ass here, but if you are playing fallout 3 just for trophies you are playing it for the wrong reasons.
What i think he means is that hes upset at the long hours spent on this Char, and that the only "Soloution" is to do it again.. kinda makes ya feel bad for yourself, after spendign so much effort and time creating and moulding that char..
Just like i have, spent about 30hrs myself, only at Lvl 18, but have done alot more quests and exploring then i did when i completed the game a few month back. was at liek level 25 with all DLC's completed and Main quests completed, but literally didnt do anythign else, only things i "come Across" rather then "Finding" everything to do..
