Dissidia 012 [duodecim] Final Fantasy Legacy Edition

In case you don't know, Duodecim is a prequel to the original Dissida. The story takes place in the war prior to the one in Dissidia (13th war), hence why some of the heroes will be on Chaos' side.
Quite a few new characters have been added, there are 6 new defaults (Lightning, Vaan, Yuna, Laguna, Tifa and Kain) and 3 secrets (Prishe, Gilgamesh, Chaos) from various Final Fantasy titles. This brings the total number of playable character to 31. While most of the new characters are quite unique in term of play style, for example, Tifa can feint most of her attacks with a teleport, Lightning can change into different movesets with Optima Change, Laguna has some interesting tools such as a sniping attack; some play a bit too similar to the original characters (Yuna is too much like Tina/Terra). However, all of these characters are still great additions nevertheless and is probably the best thing about Duodecim.
The story mode for Duodecim is really short; there are only a handful of chapters to complete, which shouldn't take you more than 10 hours. However, it's good to know that the original Dissidia story mode is also present in case you want to play it again (that's another 40 or so hours if you haven't played Dissidia). Gameplay has been improved by a tiny bit. The most noticeable one is Chase Battle being much faster this time. Other improvements involved A.I fix and some balancing. No new moves for the original characters unfortunately.
Even if you have already completed Dissidia, the replayability for this game is still pretty high. There are quite a lot to do. Arcade mode is there if you want to go old school, Free Battle is great for setting up that epic fight, PP Catalogue has been updated with new stuff for you to obtain (e.g third form/costume for all characters). Last but not least, Battle Replay, which I think is the coolest feature in Dissidia also makes a return. In case you don't know what it is, Battle Replay allow you to save your match, watch or edit it and then encode it into a movie file, all within the game.
As a prequel, Duodecim falls short due to its limited story. But as an expansion, it is exceptional. If you're a fan of Final Fantasy, this is the game you need to have.

Square Enix pulls off another awesome game. This game offers excellence from the story to the action. The fighting style is relaxing yet intense simultaneously. A good game to play for hours without boredom. Very similar to Dissidia One, but the 6 new characters offer a bit more gameplay.

A good game that has some flaws and could have done with some different characters that are if not more popular but as popular as the ones on this game.

When I saw this game and read the reviews I thought hey why not, but after playing this game I was blown away! This game is incredible and easily one of the best PSP titles around. The gameplay is a little tricky at first but once you get used to it you will find it hard to put down. 5 Stars… easy

Thoroughly enjoying this game, though it is an extension of the original Dissidia: Final Fantasy. The game comes with more characters than it's predecessor, sadly not the legendary Soldier 1st class Zack Fair.

You have the option of downloading a 3rd costume for many of the characters from the PSN Store, along with many of the music tracks that have appeared throughout the series.

If you purchase Duodecim Prologus from the Playstation Store you can unlock Aerith from FF7… Though she only appears as an assist character it is still well worth it.

Something that really rocks about the game is that if you played the first Dissidia, you can transfer your character levels across to this game.

The graphics are fantastic, and the new world map is a definite improvement from the last game.

As for multi-player, the game allows you to WLAN with other players for 1-on-1 battles, but there is an absence of online battles which would make the game exceedingly better and more challenging as the fun seems to leave the game when you can slice opponents in one slash.

Now… Legacy Edition or Standard-
I say the Legacy edition is the one to go for… While the game is the same, and it's not exactly the greatest Collector's edition that Square Enix have ever released, who can argue that the extras aren't worth the cash.
