Just beat Suikoden 2 this weekend. Overall it was really fun, but not one of the best RPGs I've ever played. It was fun collecting the 108 stars and all the other collectibles like recipes and garden items and etc., but I didn't feel like any of it had any impact on what I was doing. I know I could have used any variety of parties but I tended to stick with the characters with story impact. Also, the unites and runes were cool but very limited and in the end you are just left with a traditional turn-based battle system with standard experience levels. Also most of the runes were useless and it sucked that only a few characters had 3 rune slots.
I will say that Luca was the best part of the game and it was actually sad (SPOILER)to see him go so early. I was hoping he'd be the final boss. That was definitely one of the most intense boss fights I've ever played and his absolute ruthlessness leading up to it played a large part.
