Technically, it's better looking than Final Fantasy XIII running in DirectX 10 and there are a few patch revisions out. You could purchase PC version off Amazon about 4 months ago. A lot better with patches, and better than X360 to begin with.
As an admittedly picky game player, and having played enough RPGs to know "good" from "bad," I definitely think that the good parts of The Last Remnant outweigh the bad. I will jump right into the parts of this game that I enjoy:
1. Outside of the battle field, the game has stunning scenery. While there are standard caves and dungeons, there are vast and beautifully detailed outdoor environments that are very refreshing and energizing. Some of environments are very reminiscent of the "Myst" series, which I particularly liked.
2. Along with the scenery, there are some stand-out tracks on the soundtrack. Namely "Old Traditions, New Methods" and "Rolling Hills, Sprawling Plains." Many tracks have a very eclectic, new age feel. Unfortunately there are some uninspired electric guitar battle themes, but the composers more than make up for it with the better tracks.
3. There is a geniune sense of free adventure in this game. The story line is set up for you from the beginning, but the majority of the game is spent exploring areas through side quests. Through these sidequests and exploring different maps, you can open up new cities, landscapes and dungeons that have nothing to do with the immediate story at hand. Whatever your mood, you can satisfy yourself in this game. At almost any time during the game, you can choose between free roaming, completing side quests, or progressing with the main story of the game.
4. No matter where you go, the enemies usually seem to be programmed to fight at your level. Of course, there are difficult boss battles that you must level up your characters to win. However, for the vast majority of the game, there are no sudden huge spikes in difficulty that plague some games (like Star Ocean 3). You are able to save at any time you can open the game menu (99% of the time), and you are fully recovered after every battle. That said, regular encounters are a little more drawn out and less frequent than, say, Final Fantasy XII.
5. The characters have some depth! While some of the characters' stories leave a bit to be desired, you get to learn a lot about your party members and may even grow attached to them like you did in Final Fantasy X. This helps because you feel involved with their story, and it provides motivation to progress in the game.
There are few bad things that I can say about this game. The load times can be a little distracting. However, they tried to make it helpful by including game tips on the load screen. Additionally, there are some frame rate issues during battles because there is A LOT going on (by the end of the game, you can control up to 25 characters divided into 5 parties that fight at once on the battle field). However, I quickly got over that and don't even notice it anymore.
In all, this is definitely a game to check out. With the reduced price, there is no excuse not to try it out now. This is a masterfully done RPG - not completely groundbreaking, but very refreshing and enjoyable.
