Hmmm... Well, I'm not sure how obscure these are, but I know the Saturn was not a big hit for some reason.
Dragon Force: I think it was a Working Design title. It's kinda hard to describe. There were 8 kingdoms to choose from, and you chose the monarch you wanted to play through the game with. The goal is to unite the 8 Warriors of the Dragon Force (who happen to be the 8 monarchs). War has been declared by one nation on the other seven, so the continent is in state of...well...war. So basically, you must conquer the continent, capturing castles and trying to turn captured generals to your cause.
The battle system is great, and I haven't seen one like it since. When two armies meet, you choose one of your generals to battle one of the enemies. Both of them are on the battlefield with their armies (up to 100 troops each). You give orders for formation and the like as well as perform some special attacks that damage either troops, the other general, or both. There are several classes of troops, none of them unbeatable. Kinda like rock, paper, scissors.
I can't write enough to detail all the great things about this game, but ^^ that's not too bad.
Blazing Heroes/Mystaria: I have yet to meet another person that has played this great game. It's a tactical RPG in the same vein as Final Fantasy Tactics. You move around on a grid-system and execute attacks over specified effect areas.
The maps were great as were the overall graphics. The story was about saving the world and assembling the chosen warriors and all that, but it was a great game to get immersed in. There are sidequests and even an arena, and the enemies get pretty crazy towards the end. Another great game for the Saturn.
Hope these were obscure enough,
