Trying to get back on topic now...you know, it's amazing exactly how many game threads turn into FF discussion threads. The madness never ends...
SEGA GENESIS
Mutant League Hockey - A hockey game where all the teams consist of monsters, mutants, robots and other ungodly beings. You can either win a game by scoring points, or beating members of the opposing team to death with various weapons. A very fun game to play.
PLAYSTATION
Lunar 2: Eternal Blue Complete - I thought it was better than Lunar 1, to be honest...it's a lighthearted RPG with a very well developed cast of characters. A must have for RPG fans. Like Lunar 1, Eternal Blue comes with some goodies. It comes with the hardbound instruction manual, character standies, the game soundtrack, a "Making Of" movie, and an actual replica of Lucia's pendant.
Valkyrie Profile - Fan-friggin-tastic game. Gorgeous graphics, a great soundtrack, and one of the best battle systems ever to grace an RPG.
Tales of Destiny II - The story is a little cliche, and the voice acting definately isn't the best, but the fun battle system and large number of minigames and sidequests will keep you busy for a long time. Great RPG.
Xenogears - Just go out and buy this game.
PLAYSTATION 2
Breath of Fire: Dragon Quarter - One reason to get this game is because you're getting an excellent action RPG for a cheap price. It's got some very interesting gameplay features and smooth cel-shaded graphics. Also has one of the best soundtracks I've heard in a long time.
Guilty Gear X2 (The Midnight Carnival) - Without a doubt one of the best 2D fighters ever made.
