Well, I didn't wait for reviews after all. I picked up Sigma Star Saga last week, thinking it might be hard to find soon, and it's definitely cool.
Bad: I'm not happy with the story so far. In particular, the characters are not very likeable. They all have too much attitude, and the main character's reactions often seem out of character. One minute he hates someone, the next minute he has the hots for her. Still, the plot offers some intrigue, so it's not all bad.
Good: The gameplay is fun and unique. The land sections remind me a lot of Secret of Mana, not quite as sharp as Zelda, but still good. The shooter sections are what really spices things up. I was disappointed in the controls in the first shooter section of the game, they seemed pretty sluggish, but the current ships I'm using seem better and this being an RPG, I bet/hope that the ships will become even faster as I earn experience.
