Shadow Takes Chaos Control in First Sonic the Hedgehog 3 Trailer
This list is being made before the release of Sonic X Shadow Generation, and just covers the content seen in trailers and gameplay footage (as well as the original game) so far. If any more games are added to the lineup, this list will be updated to include them.
11Honorable Mentions
Optional Reading Material.
Now you might be thinking: “Why would there be an Honorable Mentions in a list like this?” But Sonic X Shadow Generations has a ton of games represented that aren’t given full levels (or only exist in the long-neglected 3DS version) and mostly just have music or art in the game. Here’s those smaller games:
As an aside, I’d be surprised if we didn’t see the additions of Sonic Lost World, Sonic Mania, Sonic Dream Team, Sonic Superstarsand potentially Sonic Rumble to this listin the future, but we’ll just have to wait and see on that.

10Sonic Origins
Four of the Classics in Mildly Playable Form!
For Sonic 1, 2, 3, Knuckles and CD I decided to just combine them all into the collective Sonic Origins package, becauseeven though this collection was disappointingto most people, it’s easily the most accessible way to play the classic Sonic games.
It’s got full 16:9, modernized remasters of all four classics and it’s also got Sonic 3 with a debatable worse soundtrack. Still, these games represent 3 levels, 2 bosses and a pinball machine in Generations, so it’d be weird to skip them.

Sonic Origins Plus
9Sonic Adventure
Sonic’s Pretty Dang Fun Transition to 3D.
The main issue is that this game isn’t really accessible to a majority of Sonic fans, which is going to be an ongoing theme these next few games. The best version is either the Dreamcast one or on PC with mods, but if you want to just watch a playthrough instead of dealing with all that, that’s fair.
Sonic Adventure
8Sonic Adventure 2
Great Game, Hard to Play Nowadays.
In a similar boat to the previous game,Sonic Adventure 2 is unavailable on all (non-PC) modern platforms, yet it’s one of the most important games to Sonic X Shadow Generations. It was the start of Shadow’s existence, after all.
Pre-Orders Hit the Starting Line for Sonic X Shadow Generations Collector’s Edition
Sonic fans can now put in their pre-order for the very jampacked Sonic X Shadow Generations collector’s edition being offered via Limited Run Games.
It’s a fun game with a ton of story beats that lean weirdly melodramatic yet awesome all the same, and it’s super important to at least watch a playthrough of it if you can’t get your hands on it due to it not being widely available at the moment.

Sonic Adventure 2
7Sonic Heroes
Great if You’ve Got a Gamecube.
Sonic Heroes
6Shadow the Hedgehog
One of the most Important Ones, Somehow.
It’s fun to breeze through some of the routes (though others can be quite grindy) and it’s got incredibly important story beats for Sonic X Shadow Generations,considering Black Doom from Shadow the Hedgehogis a main player. I’d still recommend just watching a playthrough, though.
Shadow the Hedgehog
Iconic, Ironically Enjoyable and Crucial to the Lore.

4Sonic Unleashed
It’s Werehoggin' Time.

3Sonic Colors
Finally, a Game You Can Play.
For the first time since the first entry on this list, this game is actually accessible on all modern platforms due to Sonic Colors Ultimate,a remaster that by all means is not good, but it at least maintains most of the original charm and fun of the game (while butchering the visuals).
Graveyard: Sonic Adventure
It’s got a whole one stage in Generations if we aren’t counting the 3DS version, and that stage is great on aesthetics at least, and Colors is just a really solid, fun game in general, so it’s worth going and playing it. You should probably play the Wii version if you may, but the remaster does, in fact, exist.
Sonic Colors
2Sonic Forces
Not Great, But Most Likely Important.
Onto games that came out after the original Generations, Sonic Forces has (at least) one level in Shadow’s Campaign, and I’d be surprised if we didn’t get a rematch against Infinite. It’s also got somewhat important story beats for Shadow’s character and it takes a whole 2-3 hours to beat.
It’s not the best game, or even really a good game, but it does frequently go on sale for around $10 on all modern platforms, and it’s fun to enjoy ironically or just consume it like junk food. Either way, it’ll be important to Sonic X Shadow Generations.
