I think the problems with the story of Shadow Generations are two-fold:
1. It exists to be a commercial for the third movie (iirc Iizuka literally admitted that Shadowâs presence in the third movie was why they made the game).
2. Itâs an apology/reset for Shadowâs characterization in the 2010s.
It doesnât feel like the game was made because Sonic Team had an idea for a story and wanted to tell it. It feels like it was made to be an advertisement and to reassure fans that yeah, we know we fucked up Shadowâs character for over a decade, but we promise heâs better now! Please give us money again!
LikeâŚthey bring Maria and Gerald back but they donât give them anything to do or have them experience any kind of character arc and I will never get over Gerald not being fat. They didnât have any real ideas for how to use them; they just needed them there so newcomers know they exist and so long-time fans will get to see Shadow be nice to them and thus be assured heâs not a douchebag anymore.
They bring Black Doom back, but all he does for most of the game is troll, which doesnât make a lot of sense. In the original game, he invades in the first cutscene and then is forced to bide his time because he needs the Chaos Emeralds. But in this game, he doesnât seem to need them, so thereâs not much reason for him to wait until Shadow is five doom powers stronger to start fighting him. He talks about wanting to take control of Shadow after heâs been perfected, but shouldnât he already know that wonât work, since thatâs what he tried to do in the last game and it failed? He literally admitted Shadow was immune to his mind control.
It couldnât be more obvious that they couldnât think of anything for him to do until the final boss scene. Heâs only there to send Shadow to Radical Highway as an Easter egg for long-time fans and to tell new fans that he exists, in case they ever decide to use him in the cinematic universe.
Black Doom isnât in the game because they had an idea for a story that involved him. Black Doom is in the game so that the Black Arms soldier can attack Maria so that Shadow can save her so that Shadow fans will breathe a sigh of relief that he actually gives a shit about helping people again and isnât a one-dimensional asshole anymore. And, of course, so newcomers will see Shadow do something cool and thus want to see him in the third movie.
I get that Generations is âEaster Eggs and References: The Game,â but if youâre going to bother with doing a storyline, you should commit to it. The references should serve the story and instead it feels like the story exists to serve the references. Alternatively, itâs okay for it to not have a story! If they wanted to just make the game a compilation like they did with Mania or Sonic Mega Collection, thatâs okay! Iâm sure my nostalgic ass would still buy it. But if youâre doing a story, you should actuallyâŚya knowâŚdo a story. Not just references and introductions and a commercial/characterization reset button pretending to be a story.
For all its flaws and all its bad ideas and plot holes, Shadow 2005 feels like they really did have an idea for a story and wanted to tell it. It doesnât feel like a commercial or a Sonic Wiki page or an apology. Thatâs something I wish Generations had.
