The hate is well founded. Every Tales game is exactly the same. The only thing that ever changes are some static naming conventions... and that's it. It's the reason how they are able to pump out the games they do. Their entire creative process consists of is changing the elemental's names and collection themes (harness the 8 elementals,find the 8 swordians, defeat the 8 craymels,visit the 8 temples, and so on) and little else. From there... they the rehash light-fantasy-anime settings by merely changing the names of STARTING TOWN, FORREST TOWN, DESSERT TOWN, GHETTO TOWN, UPPER CLASS TOWN, SNOW TOWN, and DOCK TOWN. After that... throw some characters together with assorted colours, hair cuts, and cookie cutter personalities and voila... you have all you need to create a new Tales game. The fight system... the items... the enemies... SKILLSETS... the story... everything about the series is a rehash of a rehash. It's like all of the games are running off of the same GENERIC JFANTASY mad libs sheet. They invent some fantastic crisis that throws the characters across the map to save the world... and that's it. It's disgusting.
Tales of Eternia did it best though.... but they fucked it up by making that embarrassing anime series and the soul crushing MMORPG sequel.
