Euphoria - I'm 55hrs in, and am only 75% of the way through, with lots of sidequests left.
I'll give you a hint: You always want to back track once you've completed a major line of quests. Once you get the chance to return to Nor after some events, go back ASAP and revisit the main continent to start with some major sidequests. I totally missed the uber-monster hunt because of it. Although you can always fight them, you won't get the bonuses.
There are the following sidequests available:
Warehouse Challenges (puzzle game)
Giganto Monsters (Uber-enemies with health higher than most bosses)
Casino Games
Delivery Quests
Mini-Quests (like special cutscenes/skits when you return to an area at a specific time. Hence the focus on backtracking).
Cooking
And so on. There's a lot to the game. I have maybe 60% of the skits unlocked, and it's crazy to think how many more could be available.
Back from the dead, I'm afraid.
