I'm currently 11 hours into Radiant Historia, and I'm having a good time with the game. Interesting time-travel concept and intuitive combat mechanics. No random battles, which is a plus.
One thing I can't give it points for is the lame characters. Fortunately for Radiant Historia, it's an age-old problem not specifically isolated to or exemplified by this game, so I'm not singling it out; it just so happens to be the game to inspire my rant here.
The problem I'm noticing with these RPGs is the lack of balance or variety in character mood. The characters are either nauseatingly bubbly, hopelessly aloof, or militaristically stoic. What happened to charisma? There is a disturbing lack of charisma and charismatic characters in RPGs today. I'm talking genuinely charismatic characters, and not some cynical twit that hides his or her personality deficiency with a heavy dose of sarcastic remarks.
I'm definitely going to finish Radiant Historia, but I was hoping it would bring something fresh in the character development department.
