It really is a good game. I started a new game recently and have managed to keep all members loyal(thanks for the advice by the way) with only 2 members left to join.
What do you mean keep all members loyal? I'm at about 15 hours and i think halfway done or so. No one on my team has died or anything. The only person i wish would've joined was amber from horizon, i thought her and sheppard could have some sexy time. And my hints keep saying there isn't dating so you need to talk to people to have a relationship, how can i get intimate with one of the team members?
As you advance through the game your team members start asking you for help with a personal problem. When you do their side missions you can their loyalty. If fail the mission you don't. After gaining loyalty it is easier to start relationships with them.
