Guardian Heroes/YMMV

And the Fandom Rejoiced: At the announcement of the remake on the Xbox 360.
Crowning Music of Awesome: "Rough and Ready" from the original Saturn game. It even made it into Advance Guardian Heroes as the music you hear when battling the other heroes.
Game-Breaker: In Advance Guardian Heroes, Dylan, arguably. His down-aerial sends him tumbling down toward the ground and landing with columns of flame shooting up around him. It has one of the highest priorities in the game, renders him effectively invincible until it finishes due to that priority short of perhaps the final boss's auto-stun eye, and does reasonable damage in a fairly wide area as well. His down-ground attack is a spinning leg kick with lots of knockback, decent damage, and also has high priority. His side-ground attack is a bit slow starting up, but does a lot of damage, and also stuns the target momentarily like a lightning spell does. His stats are well-rounded, and his lightning spellbook is nothing to laugh at either. This kid's in-story performance does not do him justice.
Good Bad Bugs: In the Saturn version of Guardian Heroes, it's possible to start a new game on Easy, quit, switch the difficulty to Hard and then resume playing the game on Hard mode with 99 continues.
Most Annoying Sound: Super Zur's laugh
Polished Port: The HD re-release on Xbox 360 has (optional) HD graphics, an improved English script, online co-op, a bigger Versus Mode for up to 12 players, and a Remix mode that completely changes how the game is played.
That One Attack: The final boss' flamethrower in Advance Guardian Heroes. Get hit even once, and the rest of the attack will completely annihilate your health meter.
- Kanon's Ice Circle in the original game. He'll spam it repeatedly, killing you before you can even move.
That One Boss: Kanon, Xenovia, the Sky Warrior, Super Zur and especially Golden Silver.
