alot of games dont have trophies, but what would make my day is if new vegas has trophies, kinda like, finishing the game's main story on hardcoe without ever changing the difficulty could give you the package (not whats inside it, itd be a bit of a spoiler for for other players lol. what do you 360 players (or people in general who know what the bliviongate: im talking about lol)

...the 360 has Achievements. They work just the same as the PS3's Trophies.

Yeah....considering that the console is 5 years old, you'd think that would be common knowledge...

Theres already a trophies/achievements thread right here on the frontpage.

I feel like the OP had no idea what he was saying..

trophies, not achievements,

Uh, no games on the 360 support trophies.....thats only for PS3. Trophies and achievements are pretty much the same thing.

aka a huge d*ck waving competition.

I think the OP is talking about something else, like in Resident Evil 4, if you finished the main game and one of the mini-games + $1,000,000 you can unlock the "Chicago Typewriter" Tommy Gun which had infinite ammo, which was a cool, but ultimately game-breaking item because of ammo scarcity and the ammo management was part of the game's strategy. Luckily you have already finished the game first... =p
