I didn't download all of the DLC if that is what youre asking. one DLC was included with my game, was getting that Geth dude and Zaeed . I recruited as much as possible. But the PS3 version has all of the DLC included so there are some extra characters for me to recruit.
THen I upgraded every possible weapon and ship add on as well as do everything that was in my journal. I also had a relationship with a crew member and saved everything but Jack and that cute receptionist girl. That was because I didn't type into the add on stuff until i was done with the main chips crew. So because I didnt go into the final mission immediately, my crew suffered and I didn't get loyalty with Zaeed.
I am already 14 hours in and I've recruited Zaeed, Garus, Grunt, Kasumi and Mordin. The bolded ones are loyal already. So I'm playing at a pretty good pace.
