Actor Existence Limbo: Hirotaka Suzuoki, who voiced Bright Noah, died between Another Century's Episode 2 and Another Century's Episode 3: The Final; all of Bright's lines in the latter are taken from the first game.
No Export for You: Due to the ridiculous difficulty in licensing all the mecha, it will never see release across the Pacific.
Post Script Season: Mobile Suit Gundam SEED Destiny is already over by the time Another Century's Episode: R starts; the first stage has Shinn, Kira and Athrun Zala facing off against an unknown enemy using Earth Alliance mobile suits.
Preorder Bonus: Another Century's Episode: R has Amuro's custom Zeta Gundam, originally seen in the IMAX film Green Divers and later in Gundam Evolve.
To be more specific, everyone can unlock it. The pre-order code just let you get it earlier than normal.
Considering SRW brought in characters from Hero Senki and Great Battle, and Another Century's Episode is pretty much just SRW run through the Armored Core filter, this isn't as far out as it seems.
Now there's a bit of reciprocity, if not, complete Irony: Super Robot Wars own Original Generation are part of Another Century's Episode: Rs lineup.
And now the Geshpenst models from Portable are appearing in Original Generations 2, so it's not really an Urban Legend anymore.
What Could Have Been: On Banpresto's official blog, Word of God said the team's first choice to round out the Zeta Gundam cast in Another Century's Episode: R was Four Murasame piloting the Psyco Gundam, but because of game balance concerns and a lack of weapons, they ultimately went with Amuro and the Dijeh instead.
Macross 7 was also considered for inclusion in ''Another Century's Episode: R, but the design team couldn't figure out a way to make the "attack with music" system work in Another Century's Episode. They ended up replacing it with Macross Frontier, which caused the game to be delayed about a year while they changed things around.
