Classic.
When you first start your console, the game may seem terribly shallow, with a single option available in the initial menu, but after you save your game once a few more items tend to appear in that same menu. Obviously, you can simply enjoy the story on its own, following the very same events that the original game would present you, but this particular port also comes with a few improvements.
The biggest new feature is certainly the arena, which works as a small management game. Initially, you get to pick your monster among a certain number of similar elemental creatures, but this small critter will eventually evolve in a much more powerful beast, depending on how you manage him. You can take it into some battles, or to field, in order to improve its stats. What's great in that particular feature is that, by winning battles, you'll also receive extremely rare items, ones that aren't available in the normal game, and yes, they are well worth it; some of those improve your stats, others may grant you a high counter rate, but there are also the usual consumables, such as "Elixir".
Apart from this addition, this new port of the game is also crowded with extras. You can access an item listing, a bestiary, see certain in-game cutscenes, and even check for the locations of some items. Sure, it's not like you'll spend limitless time browsing the information here available, but at least it gives some extra appeal to the game, even if some of the items (and beasts) are terribly hard to find, or perhaps rely only on randomness.
New features aside, this game is still an impressive experience. Its storyline talks mostly about time travel and its repercussions, to the point where almost every action you take changes the future, and gives you some extras. Although the game still has some of the classic RPG flaws (when you're asked to take your options, sometimes you're not fully allowed to take them), there are also quite a few number of times where you can actually make an impact in your own experience, and that leads to one of the several endings this game has to offer; now, there are more than 10 different ones, waiting to be unlocked when you fulfill certain conditions, and that obviously adds some more play time (and replay value) to this particular title.
In terms of gameplay, this game is a classic RPG. You have to explore maps, talk to people, and fight several battles, before reaching the next storyline sequence. In that particular point, this game is just awesome - although you're presented several cutscenes, you'll never feel like they're too long, or too irrelevant; instead, each cutscene you get to see has a very set purpose, and the game hardly ever bothers you with all the specifics. One of the first episodes puts you in a quest to save Marle, and you have to do exactly that, without any cheap dialogues in your way there.
