One thing I liked about Danthegeek's Underground Hideout was that when an achievement or quest was completed it add something to the decor of the hideout. Like Boone's NCR Berret or a robot in the fish tank for killing / opening House's Life suport chamber.

If it were possible to get or make trophies what kind of thing would you like to see.

For me I would like to make a Deathclaw mounted head. Like the double brahmin headed wallbanger that we can see in the house crafting part of the E3 Trailer.

It would be nice if you got something for beating the game on hard or survival mode for your next play through. In game rewards are always a plus. Even if its just a new hairstyle or a cape or an extra bobblehead or something.

I also really enjoy achievements for playing on harder difficulty levels. I don't know why... achievements are pointless, but I MUST HAVE THEM.

That would be great if they stick to the same basic format as with FO3 and FNV and not make the game become a tedious exercise just to get an achievement.
