I love RPGs, and I must say the same thing. And I've even played other games of the Tales saga, but it's Symphonia the one that appeals me the most. Not just because of the story but also for the characters and the chemistry between them.

I'm glad I'm not the only one who thinks they even have similar personalities x'D
And yes! I knew about Zelos and Genis. When the 3rd Hetalia DVD was out, I was claiming that the cover was a wink to Zelos/Lloyd x'D

In fact, a couple of days ago I found a REALLY cool fanart related to that. I'll show it to you later 8D
