A Narcissistic Birthday Train! (UPDATE: solutions posted)

So my birthday was on Monday (1st June) but I was too busy with job interviews to celebrate properly. Still have my cake in the fridge. Party was postponed to this weekend and you're all invited, but in case you can't make it, here's a short giveaway train to compensate.

Word of warning: You're going to learn quite a bit about me when you're done :)

Ok, time to pay for your ticket
Train contains both bundled (Lvl1+ required) and non-bundle (Lvl3+ required) GAs. Ends Sun 6pm GMT

Mood music

UPDATE: Q7 edited for clarity

UPDATE 2: Thanks everyone! Had a great time here and at my party. All keys sent to GA winners. If you got on the train but didn't win, don't fret, I have another surprise planned ;)

UPDATE 3:
For all those who got on my train but didn't win, remember the valuables you left in my safe in the first carriage? Well, something weird has happened....they've all morphed into game keys! Quick! Check if any of them are yours!

NB: GA winners will find they're now on my blacklist. Don't fret, it's only temporary. Have to spread the love around :)

Final update:
OK, now I'm really done :)
