Xenoblade Chronicles

- You have to put things into the collection by hand, it doesn't happen automatically

- Whenever you see someone with a blue dot, speak to them. What they say will change as you do more sidequests, relationships in the affinity graph change and as your affinity with the area they're in goes up.

- There are literally hundreds of side quests, though they entirely optional

- If you have a quest with a clock icon, that means that you can miss it by advancing the plot so far. I've only been through it once, but as far as I can tell, the game does warn you when you go past a point of no return.
