Rudra's Treasure had a pretty great premise, decent music, and really nice graphics, but the game itself is absolutely atrocious.
Like, the battle system is about as functional as the RPGMaker DBS. The most exciting things you're going to see out of it are the weapons that hit more than one enemy per round. It's not like Final Fantasy 6, where you had this huge variety of really cool shit to use, like Blitz/Jump/Steal/whatever, or items like the Genji Glove and Offering. The fighting in this game entirely boils down to "whats this guy's weak element", wearing the newest equipment, and healing every 3 turns.
yeah, so basically the most fun part of Rudra's Treasure is

putting rude shit into the mantra system. FUCKBONERS
As far as what I would recommend though,
Treasure Hunter G,
Robotrek,
Live A Live and especially
Terranigma are all really really good. Terranigma has one of the best endings for any game ever.
