I just finished playing New Vegas (again) and went on continuing my Fallout 3 run.
I have to say, coming from a hardcoe New Vegas game, the simplicity of Fallout 3 is ... surprisingly refreshing.
- No longer do I have to collect endless amounts of crap because there are just a few crafting recipies. Most of the stuff I can sell without a worry in the world that I might need it for something later.
- I actually like how Fallout 3 handles the food and water issue. I regularly eat and drink in Fallout 3 because it's a poor man's stimpack. No need for hardcoe mode. Actually I eat and drink more regularly then in New Vegas. And I don't have to give a damn about storing food for the future. In my New Vegas game I diligently stored and crafted food ... and ended up using NONE of it. All the Desert Salads, Caravan Lunches and Gecko Kebabs are totally unnecessary. I ate simple steaks for the whole durating of the game.
- All those Ammo Crafting recipies and the crap that comes with them! Who actually crafts ammo? I don't know, I found it to be far to tiresome for the results it provides. I'd rather go kill a Legion Assassin squad, sell their stuff and buy ammo.
Which kinda leads me to the conclusion that Fallout 3 might be better in this respect. Fallout New Vegas has to much useless (or virtually useless - because you never use it anyway) crap which just fills up your inventory or gathers dust at your homebase.
