Here are the ones I came across that I remember.
Which of these was a vehicle in Twisted Metal 2012?
In Jak and Daxter, who was Jak's love interest?
Who is Parappa's girlfriend?
Where was Kratos born? (I got a laugh out of the fact that they had Detroit as one of the answers)
There are more that I came across but these are the only ones I can remember at the top of my head at the moment.
