Count me among the people who failed to save Lucca's mother and failed to wait for Shadow on the Floating Continent. And felt AWFUL.
I'm also a (sort of notorious amongst my gamer friends) theorycrafter, who writes detailed builds for characters in RPGs like Diablo or Torchlight (esp. Diablo II) and then maybe quits after I get to level 50. Or, you know, level 5. If I'm having second thoughts about where I spent my first few points, then I panic and start anew. I'm finicky.
