As with the Origional, Zero is a true work of art. The Generation system is vastly improved from the original, and the affection system adds its own level of stratagy. The gameplay, while at first glance appears simple, is, in a word, "Multi-Layered". Mastering Esoterica and Combination arts is key to not only surviving some of the most difficult battles, but also recieving some of the best items in the game. With that in mind, I would be remiss if I didn't mention the Agarest Wiki that contains truely invaluable information on the game itself.
While i love the game, I have to mention two dissapointments I have in concern to the actual game itself. First, the monster capture and combination system can be a boon to any player. If only for the Title System and the High End items you can get by using it. However, capturing monsters can be a chore sometimes, and often feels like a waste of time due to the grind required to max it out.
Second, the blacksmithing system has one infuriating element that i wish they had eliminated from the origional. That is the Random Item system that occures while smithing. On occasion, while crafting items, instead of the desired item you recieve a random craftable item instead. This still uses the materials, and after 3000 craft attempts, I only recived one item I cared about, or was useful. Instead you generally recive items that are either utterly useless, or are low level and already abundant.
As to the Steam download, it has one major glitch i was unable to remedy. Unfortunatly, there is a glich where on many characters in both conversation scenes and in the gallery, the characters images are obsucered by all the other alternate appearances being layered over eachother at the same time. This takes away from the character and story driven expreance that is essential to any JRPG.
On a possitive note, the Steam DLC is absolutly fantastic. Without it, many cassual gamers may find the baseline grind to level up and aquire both Gold and EP to be a daunting task. After purchasing the DLC it was almost like starting a new game + without ever having to have played the game.
I would recomend this series to anyone who enjoys JRPG's or RPG's in general. For a more epic experience I suggest playing the original and then loading over the completed game data to Zero.
All in all, I'd give this game a solid 9 out of 10.
As a simple footnote I would suggest that due to suggestive sexual content in this game, parental supervison is advised.
