IGN reports that InFamous 2 offers an option to import Trophy data from the original InFamous, which is then turned into starting bonuses in Cole McGrath's new adventure.
We've got a rundown of what your Trophies are worth in the sequel after the break -- starting XP bumps and the like -- but the most interesting bit of info is that having unlocked specific story-related Trophies will actually alter the dialog and side missions in InFamous 2. We'd tell you what they are, but then you'd have to kill us. And also, we don't know, because IGN didn't say.
Of course, you could also look at this feature as one big morality test: Will you be a goodie two shoes and choose not to import your data, or do it and effectively use a "cheat" right at the start of the game?
