Well, since most people here seemed to like Tierkreis, I'm going to voice my general dissatisfaction with the game.
But first the good points:
-There were many interesting characters. On this one I can't fault them.
-There were some good politics on a local level. I particularly like the politics of the magedom.
-The music was pretty good. Not great, but pretty good.
-The trading system was done well.
-They didn't screw up the quest system.
-Rarohenga is one of the coolest places in any video game ever. Alas, we didn't spend much time there.
And now the bad points:
-It isn't a Suikoden game. It's not set in the same world. It's not set in the same universe. There are 108 stars of destiny, but the similarity ends there. It is clear from the game that any world in that universe would have a chronicle, which is something that we don't have even hints of in the Suikoden world. I admit that this problem has little to do with the game itself and more to do with the fact that it is called Suikoden and as such has become taken in by the Suikoden fan community as canon. Furthermore, it seems likely that this has marked the end of the legitimate Suikoden series. Certainly, the game has laid the seeds for a more direct sequel. Were it not for the possibility that this is more than simply a one-time spin-off, This whole thing would worry me less.
-The macropolitics are extremely simple. Citro Village is a small, largely unprotected autonomous village in a fertile valley, and no one is trying to change that. There doesn't seem to be much in the way of internal politics in Cynas either. Everyone follows Valfred and except for a handful of people who join you, no one has issues with it. The magedom is supposedly huge but only consists of two cities, one of which is a fairly recent addition. I could go on, but I think I'll leave it at that.
-The morality of the game is childish. There is only room in the company opposing The Order for people of one belief system. Anyone who believes in predeterminism is automatically branded a bad guy. I see the game as a battle between two evil organizations that is trying desperately to make one of the organizations seem good. If it weren't for the fact that the Order is actively trying to destroy the world, I wold join up with them rather than the Company.
-The main character is stupid and foolhardy. And the game supports that. At any point in the game where someone might put in real thought, the main character doesn't, and it turns out to be the right decision. If you choose to attempt to resolve the game in such a way as to create victory for the world at tremendous sacrifice to the characters, you lose. Indeed, you can only win by doing something completely unfounded in logic.
-There aren't any runes and the magic system that replaces them isn't as interesting and doesn't have the same sort of internal consistency. There seems to be little connection between what the chronicle is and what powers it bestows. In contrast, not only is there a strong correlation between the runes and the powers they bestow, but one could make a nice bit of mythology/cosmology from the various runes.
-The big battles between nations almost never involve more than ten people on each side.
-The voice acting is painful.
-They have you buying weapons. This irritates me because traditionally, weapons aren't so easy to come by (or so different in quality) that it's worth it to buy a bunch of weapons and sell your old ones. I mean, in Medieval Europe, a new sword could well cost the amount of money a knight would earn in a year. And peasants? Well, they'd just have to attach a knife to a pole and call it a spear because they'd never be able to afford a sword. And that's one of those things that the Suikoden series got right up until now.
So that's my review.
