Heh, my fics always have a good amount of suspense. Especially Dawn of Darkness, considering it's FE. And Fire Emblem always has a lot of suspense because of the numerous battles and wars and all. I also enjoy having a major character get hurt badly and make the readers wonder if they're going to be alright.
A good example is how Ike falls very ill in DoD and it's discovered that his food was poisoned. The poison was meant for Azura, but he ended up getting it instead. So for the next few chapters, the other characters are rushing to find poor Ike an antidote.
And don't get me started on Link's injuries putting him in a coma in Zelda: The Ancient Power... Hehehe.
