Simple enough. The top five optional things in games that you regret not doing/not finishing. Mine are:

 

1) Final Fantasy XIII, "l'Cie Paragon": To get this trophy, you need to defeat all of the MArks in the game with a 5-star rating. I only have, like, five or six left. I'll totally go back and get them... eventually.

 

2) Persona 3, "The Reaper": The Reaper is the second most powerful enemy in the game, and has destroyed me as such. He can technically be beaten once you reach level 70, but I never did. I'm playing through again, so hopefully I'll get him this time.

 

3) Final Fantasy XIII, "Treasure Hunter": Hold every item in the game. WTF?! Again, I'm about halfway there. I'll do it at some point.

 

4) Soul Calibur III, "Night Terror": I never fought Night Terror in the story mode, only in the missions.

 

5) L.A. Noire, "Finish": I still haven't finished the game. I watched my sister play ahead of me a while ago and I still remember the cases. I want to do it completely on my own without knowing what's coming next. Just a matter of time...

 

What about you?

1.) Tales of Symphonia- Optional bosses (I haven't finished the game yet, but would've like to fight the bosses.)

2.) Kingdom Hearts 1- Kurt Zisa and The Phantom

3.) Kingdom Hearts 358/2 Days- Not getting playable Sora and King Mickey (Those missions were a pain...)

 

I don't have a top five exactly, but it's what I could come up with for now.

1. Pokemon Red- Not catching them all. I was three away too...

2. Kingdom Hearts- Not challenging the Olympus Collesium's best cups. I wish I could go back, but my file is gone.

3. FF XIII- Platinum Trophy, so close, yet FF XIII-2 came out.

4. Dissidia 012- Labyrinth, It was just so annoying!

5. Pokemon - Not getting the special Johto starters. I didn't realize your team couldn't change...

1) Never having purposely acheived any trophy because all I care about is the plot

2) I don't ever feel like trying to either

3-5) 1&2

1) Kingdom Hearts I and II: The secret endings. I'll do unlock them next time I play through them...whenever that may be...

2) 358/2 Days: The secret journals. I got quite a few of them, but not all.

3) Crisis Core: Saving the little boy's mother from the burning house in Nibelheim! :'( (I tried, but failed miserably, and I wanted to get on with the story)

4) FFVII: Uncovering more of the side stories (I uncovered Vincent's and Yuffie's side stories, but I'm pretty sure there were more I could have uncovered).

5) Entire KH series: All the extra bosses--Sephiroth, Unknown, Vanitas Remnant, et cetera. I'll get to them someday...

That reminds me. I also never beat the WEAPONS in FFVII. I should probably do that too...
