StingingVelvet: Shit man, the only one of those I know anything about is Tekken, and I don't care about it.
You have never heard of Soul Calibur? Seriously? It is considered by many to be the king of 3D fighting games.
As for Enslaved it is kind of like Jak II meets Uncharted meets God of War meets Dragon Ball (it is based off of the story that inspired the original Dragon Ball).
Eternal Sonata is a JRPG based on the classic composer Frédéric Chopin's final hours. He is on his death bed & you play through his dream world.
The Tales Series is my all time favorite RPG series. They are action JRPGs & I would be willing to bet that you have at least heard of its most popular US game.... Tales of Symphonia for the Gamecube. If not I would highly recommend the series if you are a fan of the Genre.... particularly Tales of Vesperia for the XBOX 360 & (soon to be) PS3.
trusteft: Or doesn't like them. I know it's deep, but consider it.
To each there own I guess... you can't judge another person's taste & I don't intend to. All I am saying is that they make good games & I am surprised that you don't like any of those games. Namco is quite possibly my favorite publisher simply because of such titles.
