Super Robot Wars Gaiden

Super Robot Wars Gaiden is the first Original Generation game...EVER.

That said, it was released on the Super Nintendo Entertainment System in 1996, and for a SNES game, it featured the best 16-bit graphics ever, mecha drawn to scale (averting the Super-Deformed formula), and had a storyline that made Super Robot Wars 4 look like Fan Fiction. Suffice to say, this is the best Super Robot Wars on the SNES.

The story of Gaiden tells solely on the origins of the entire Masou Kishin cast, and the genesis of the long feud between Masaki Andoh and Shu Shirakawa. The plot is split into two parts: "Part 1" occurs prior to the events of Super Robot Wars 2, while "Part 2" takes place following the end of Super Robot Wars 4. Also, this was the first SRW that could have been released for localization, but it's rather racy, risque dialogue sadly made this a No Export for You. It's also the first SRW to incorporate voice acting.

An Updated Rerelease for the Nintendo DS was out in 2010, under the name Super Robot Wars OG Saga: Masou Kishin - The Lord of Elemental, linking the game up with the rest of the Original Generation series. In October 2011, a Play Station Portable sequel entitled Super Robot Taisen OG Saga: Masou Kishin II: Revelation of Evil God was announced, and released on January 12, 2012. To mark the 15th anniversary of the Masou Kishin series, a new Updated Rerelease of the original game will be bundled with Revelation of Evil God, complete with enhanced visuals and extended voice acting.

Tropes common to this game are:

"Saphine: "Oi oi...""
 * Alternate Company Equivalent (After cutting their deal with Banpresto, developer WinkySoft released Seireiki Rayblade, which is very similar to this game and full of Captain Ersatzes)
 * Bag of Spilling (Several units from Part 1 lose their upgrades after the timeskip to Part 2)
 * Bottle Fairy (Rebecca "Becky" Turner. In fact, when she's drunk, which is often, she tends to strip topless)
 * The Cameo
 * Combination Attack (Revelation Of Evil God finally gives some combination attack options, including Masaki-Lune, Yang Long-Tytti, Mio-Precia)
 * Copy Protection (The DS rerelease has A LOT of intentional bugs should you play a pirated copy: first, you may not be able to get the game to run at all. Get past that, then Mooks start One Hit Killing you; get past that, then Shu will always One-Hit Kill you when he's required to just lower your HP to critical; get past that...well, the game may finally run normally...except the music and everything is in SNES quality rather than what the DS offers)
 * Downer Ending
 * Five-Man Band
 * The Hero: Masaki
 * The Lancer: Yang Long
 * The Big Guy: Ricardo; succeeded by Mio
 * The Smart Guy: Xenia
 * The Chick: Tytti
 * The Sixth Ranger: Lune (sometimes doubles as Masaki's other Lancer)
 * Foreshadowing (At the end of the game, )
 * Gaiden Game (On the face of it, this is entirely true: Part 1 can effectively serve as canon to the Classic/Alpha/Original Generation timelines, and if Shu is  in any of these continuities, it sets up Part 2)
 * Gainaxing (Lune Zoldark, Princess Xenia and Simone Culian have it in the rerelease. In the sequel, Xenia gets this. In short, unless you're Tytti or Mio, you bounce)
 * Hey, It's That Voice! (Hikaru Midorikawa (Masaki), Kazuhiko Inoue (Huang Yang Long), Kikuko Inoue (Tytti Noorbuck), Mika Kanai (Mio Sasuga), Takehito Koyasu (Shu) and Narumi Hidaka (Lune)). Revelation of Evil God adds up Hiroshi Kamiya (Eran Zenozakis))
 * And thanks to Revelation of Evil God, most of the not-voiced-yet Masou Kishin characters also get some here. Aside from reprises in Super Robot Wars EX such as Shou Hayami (Rodney), Tessho Genda (Ahmed) and Daisuke Sakaguchi (Zash), there's also Yuka Komatsu (AKA the new voice of Opiochous Shaina as Rebecca/Becky), Mie Sonozaki (Simone), Unsho Ishizuka (Gennajy), Ryotaro Okiayu (Gino), Hisao Egawa (Tian), Takashi Nagasako (Lubikka) and Rikiya Koyama (Ricardo).
 * Hidden Depths (You'll get to see many of the Masou Kishin characters' depth, development and personalities, but Tytti's probably gets the most out of Gaiden, what with the lack of progress seen in EX)
 * Lolicon (Jino Varensia; his manner towards Presia Zenosakis makes Masaki worry)
 * Mad Scientist (Zet Laas Blakio)
 * Original Generation (Not the Trope Namer, but definitely the Ur Example)
 * Double Standard Rape (Female on Female): Played for laughs. At one point, probably due to shock on breast size difference, Mio proceeds to grope on Tytti's boobs much to her chargin. It's even got a picture for it.
 * Retool (Ahmed Hamdi, one of the original pilots from Arab, is at first a devout Muslim whose Battle Cry is "ALLAHU AKBAR!!". In the rerelease, his Muslim reference is removed, making him just a normal Arab, probably to avoid Unfortunate Implications)
 * In the rerelease, the names of Mio's familiars are changed into Son Goku, Cho Hakkai and Sha Gojyo, each looking like the three of them.
 * Red Baron ("Heavenly Sword" Zeoroot Zan Zenosakis and "Sword Saint" Shumel Heul)
 * Relationship Voice Actor (With the exception of Lune, all major characters have done voiceovers for Tales (series) characters: Yang Long and Mio are Klarth and Arche, Masaki and Tytti are Leon and Philia, while Shu is Jade)
 * While we're on that, each one has also done at least one role in the Gundam franchise:
 * Masaki = Heero Yuy
 * Yang Long = Jerid Messa and Gai Murakumo
 * Tytti = Aina Sahalin
 * Mio = Tiffa Adill
 * Lune = Allenby Beardsley
 * And the big one, Shu = Zechs Merquise, Gym Ghingnham, and Mu La Flaga
 * Eran = Tieria Erde
 * Shout-Out (In the remake, eventually Tytti declares lies that she's 17 years old...)


 * Suspiciously Similar Substitute (Inversed example: Mio was created first as the eventual herald of Zamzeed in EX, but since Part 1 takes place way before EX (where Mio debuts), she's replaced by Ricardo Silvera in Gaiden, )
 * Token Evil Teammate: Gaen in Revelations of Evil God. He still summons Volkruss minions on daily basis... to blast your enemies to smithereens, that is.
 * Updated Rerelease (For the Nintendo DS. The majority of plot is kept, with only a few changes made to mesh it better with Original Generation)
 * And there's going to be another rerelease for the PSP, which will be bundled with Revelation of Evil God in a special edition.
 * Vaporware (The guys who did the Fan Translation of Super Robot Wars 3 and Alpha Gaiden have been saying they're gonna do this one...for almost a decade now...)
