Wild ARMs 4/YMMV

Angst? What Angst?: Before Jude's mother dies, at least.
Anvilicious: We get it, war is bad. (But then again, Some Anvils Need to Be Dropped.)
Complete Monster: The posthumous creator of the doll twins is implied to have been one, to the point that Lambda executed him personally.
Crazy Awesome: Balgaine begins his battle with you chopping a train car into bits with his anti-tank chainsaw while riding a jetpack. Also the infamous flying with guns scene with Gawn.
Crowning Music of Awesome: Buried City
Game Breaker: Raquel, period. She's supposed to be the Mighty Glacier, but she ends up being the fastest, most mobile character in the game thanks to her "Intrude" Force Power (which grants her an additional action and can be used up to four times in one turn with a full FP gauge) and her "Move & Attack" passive ability. This basically means that despite having the lowest RFX stat (which determines turn order), Raquel can engage the enemy before anyone else and often kill them in the same turn. With the game awarding a substantial experience point bonus to the character that lands the killing blow, this also means that Raquel has a habit of blasting past the others to become your highest-level character and never looking back. Take note, she's dying in this game.
Inferred Holocaust: So, what happened to all those Wild ARM monsters rampaging throughout Filgaia?
- This is also how quite a few people view Jude's ending in the epilogue. The game says he simply became a forest ranger, but considering all the horrors he went through, it's possible the "forest ranger" part was just an excuse for him to abandon humanity and civilization. Forever. Then again...
  - Your Mileage May Vary on whether such an interpretation is truly intended or a case of Unfortunate Implications.
- There's also a certain story told by Amengard (May 7th) about the Telepath Mages....
