I don't get Fire Emblem Awakening people. They complain about the easier mode available players can take so they don't lose any of their characters, yet, if they lose their characters on the normal mode they'll close their game and restart anyways.
Those people shouldn't even be taken seriously.
When you lose a person in Fire Emblem you:
- Close the 3DS (sleep mode)
- Notify their family and/or significant other
- Cry for a little bit
- Take a few days of solitude to review how your lacking strategic skills have caused the death of *person*
- Cry some more
- Hold a funeral service with your close friends and relatives to reminisce over the good life they lived
- Put a picture of your deceased comrade on your shelf, to forever remind you of the good times you had and remind you to never make that mistake again
- Open the 3DS and carry on
Anything less than that and to be honest, you're not taking the game seriously enough.
