some of them do come that way i just couldn't resist the joke. there's some sorta Cerebus code thingy too for all the weapons. My first copy of ME2 had Stolen Memory and Price of Revenge bundled along with Firewalker which i now never do because it has no bearing on anything. Overlord and Lair of the Shadow Broker were not included.
meant to tell you guys i picked up Neriya's playthrough again and apparently we hadn't done a LOT including the Temple of Mythal. Soo she's totally drinking from the well. She bears Mythal's tattoos...an accident on purpose i think. i have gotten to the end of this game four times and i thought it was with her. Nope. Gotta stop deleting folk but it's BioWare's fault with this dumb save limit.
If you don't wish to delete some characters for good, you could try to plug a pendrive in the console and store them there: that's what I do with my xbox360 saves when I don't want to lose them forever. It doesn't really fix the save limit, but at least you don't lose the characters you're most attached to in order to make new saves.
