So I have put about 12 hours in, and I am digging the game. I got past the rather annoying puzzle dungeon MAF gave me. Hopefully it doesn't get much worse than that, but if it does, well, I'm not above using gamefaqs if a portion of a game is adversely affecting my enjoyment.
I'm digging the characters, but the plot is really not doing anything for me. I would no longer call the plot detrimental--I see what they are doing, trying to draw a big metaphor between Chopin's disappointment that his homeland was never free and the situation in his dream world--but it's just really not the most interesting thing in the world. Still, I give them applause for trying something different, and if anything, the game got me to read a few Wiki articles about Chopin's life and download some MP3s. That probably makes it a more worthwhile game than the vast majority of stuff out there.
I enjoy the battle system, but I have to echo Billy Rygar's sentiments. You only ever control 3 characters in battle, and while the game tantalyzingly teases you, it never achieves depth, or gets past being easy. The shadow stuff all sounds very interesting on paper, but once you get a variety of skills in your spellbooks, being stuck in either shadow or light is not much of a big deal. You can always reconfigure your skills to get what you want, for everyone. Similarly, the lighting hasn't been used as well as it could. Most battle fields have similar layouts--mostly light or mostly dark--so ou can always get away with very basic skill strategies.
The enemy layout is also pretty lazy. You only ever fight three, max, enemies at a time, and they are ALWAYS in the same layout. No, it's not that every party of enemies has the same layout, it's that every single group of enemies in the entire game has the same layout. I know I am only 12 hours in, but if there were going to be various layouts, it would have changed by now.
Those seem like hefty complaints, but the battle system's got the important stuff down. Battles are fast all around; fast loading, fast moving, and increasingly neat rules that make sure you are even thinking fast. This makes the game god damned fun, and the battle system never gets old, even if the game isn't very heavy on variety of combat. With a similar easy, compulsively playable quality to Blue Dragon, I will have no problems running through this game--maybe even twice for the 3 or so big achievements.
Also, I have to defend Jotaro here: Enemy variety is not the game's strong suit. Again, only 12 hours in, but I doubt this will change. Every dungeon area only has two to three enemy types, and I have seen palette swaps of MANY, if not most, enemy types already. Heck, there are at least three (make that FOUR--new area I'm in has another subsequent palette swap) incidences of me seeing palette swapped enemies in adjacent dungeons areas. Now, this isn't really detrimental to the game, or how fun the battle system is, but it is a wee bit disappointing. And come on, you are making me defend Jotaro. He was using hyperbole (there are more than ten enemy models), but repetition of enemies is definitely a valid issue here.
Oh, also, money in the game is very borked. Take one role of pictures with Beat, and you basically never, ever have to worry about money in the game. Money is usually broken in RPGs, but it's an especially broken twist here.
I am enjoying the hell out of this game though. Good show!
EDIT: Oh, overall battle system quality amongst the Tri-* games (since they all use flavors of similar real timey systems):
VP2 > Eternal Sonata > SO3 > Radiata Stories
VP2 is tough to beat. It takes the charming (but not great) system of the first and shoehorns it into an incredible realtime system with mini-dungeons in every battle field. I wish I could play that game in HD. Eternal Sonata is fun, but it could have been much better, maybe even on par with VP2. SO3 and Radiata . . .both had major issues, but Radiata takes the loser cake for being depthless. SO3 had annoying AI whereas Radiata didn't, but in just about every single area, Radiata's system was SO3 lite.
