Eggmanland hot dog missions alone bump Unleashed to the top.

Wow, that came right after the main video

This and a 3 hour marathon?! Only nathaniel can pull of something as great as this we going to be eating good tonight

Yeah, I did all routes on Shadow the Hedgehog.... casually it's gonna take you months cause you'll get tired of playing it after doing a few routes. In fact, you have to beat westopolis at minimum 326 times...

And people thought beating westopolis 10 times was tedious enough....

DLC should not be considered for 100% as that hinges on being able to pay for it to get legally unless there's a remake that includes it like casino night pinball in sonic generations.

Even kirby air riders and sonic racing crossworlds don't count anything online related like online achievements in air riders or dlc horns for the horn achievement in crossworlds.

You also missed the keys in Shadow 05 and Fire Souls in Secret Rings.

Happy 35th anniversary, Sonic the Hedgehog!

Just wanted to point out that s ranks weren't a thing until Sonic 06, And the games beforehand had A ranks

Getting the platinum trophy in Sonic Unleashed is one of the pinnacles of gaming achievement.

It's not required for any 100% criteria in Frontiers, but the Final Horizons boss rush on Extreme Difficulty is the hardest thing SEGA has ever put in a video game. I have nearly 1600 hours in Frontiers. I played it before launch. I'm a bit of a modder. It's my favorite game of all time.

I've never beaten it.

would've saved you a lot of time if you bought steaks instead of chillidogs, they have more exp.

Bro you should honestly do next 100% every Sonic racing game

It's Sonic Adventure 2. There ya go.

Well I opened YT at the right time I guess

UNLEASHED

also, there's a 2nd exploit for exp in Sonic unleashed... one of the Apotos night DLC stages gives like 1 bar of exp for each pot you break so you can easily get like 50+ bars per run. likely slower than the ring exploit, but you actually get to do stuff instead of waiting if that's your thing.
Also, I did fully beat that game using a lv1 werehog (except combat, maxed that) and it was SIGNIFICANTLY harder on the night stages

33:49 Lttle tip for the action challenges: you can temporarily set the difficulty to easy to cheese them, they'll still count (you have to get x256 multiplier and then attack a boss and most of the times that's all). And when you're done with them, bring the difficulty back to whatever you wish

Sonic Lost World 3DS has its own set of hoops to jump through to get 100%. Let me explain.

Every world has 5 levels: 3 main levels, a boss level, and an extra level. Multiply that by 7 worlds, and there are a total of 35 levels: 21 main levels, 7 boss levels, and 7 extra levels. This means 35 S ranks to get across these 35 levels (5 S ranks to get per world), and each of these 35 levels also has a Hard Mode variant, so multiply that by 2 and you get 70 S ranks across playing the 35 levels twice (10 S ranks per world across playing each world twice). Normal Mode also has an S Rank for the tutorial stage and seven S ranks for the Special Stages (one S Rank per Special Stage), so add 8, and the game has a total of 78 S Ranks to get.

Also, in Normal Mode for the 3 main levels of the first 6 worlds, each level has 5 Red Star Rings (15 Red Star Rings per world for just the main levels for a grand total of 90 Red Star Rings for just the main levels of the first 6 worlds), some of which require backtracking because they require specific Color Powers to access. Some backtracking instances are tolerable like Windy Hill Zone 1 requiring the Indigo Asteroid Color Power (the Indigo Asteroid Color Power is unlocked in Desert Ruins, the world directly after Windy Hill) for the fifth Red Star Ring, Desert Ruins Zone 2 requiring the Yellow Drill Color Power (the Yellow Drill Color Power is unlocked in Tropical Coast, the world directly after Desert Ruins) for the third and fifth Red Star Rings, Tropical Coast Zone 2 requiring the Ivory Lightning Color Power (the Ivory Lightning Color Power is unlocked in Frozen Factory, the world directly after Tropical Coast) for the third Red Star Ring, and Frozen Factory Zone 3 requiring the Gray Quake Color Power (the Gray Quake Color Power is unlocked in Silent Forest, the world directly after Frozen Factory) for the second and fourth Red Star Rings. Silent Forest Zone 3 (recommends using the Cyan Laser Color Power, which is unlocked in Sky Road, the world directly after Silent Forest) and Sky Road Zone 3 (recommends using the Red Burst Color Power, which is unlocked in Lava Mountain, the world directly after Sky Road) can even have all of their Red Star Rings collected in one run without the need of their respective recommended Color Powers. However, other levels have egregious examples of backtracking like Frozen Factory Zone 2 requiring the Cyan Laser Color Power (the Cyan Laser Color Power is unlocked in Sky Road, two worlds after Frozen Factory) for the fourth Red Star Ring, Desert Ruins Zone 3 requiring the Gray Quake Color Power (the Gray Quake Color Power is unlocked in Silent Forest, three worlds after Desert Ruins) for the fourth Red Star Ring, but the worst offenders of this are Windy Hill Zone 2 and Windy Hill Zone 3. Windy Hill Zone 3 requires the Cyan Laser Color Power (the Cyan Laser Color Power is unlocked in Sky Road, five worlds after Windy Hill and is the penultimate world of the game) for the second and fifth Red Star Rings, while Windy Hill Zone 2 requires the Red Burst Color Power (the Red Burst Color Power is unlocked in Lava Mountain, six worlds after Windy Hill and is the last world of the game) for the fourth Red Star Ring. Once you get all of a world's Red Star Rings, that world's Extra level appears (in the case of Silent Forest, collecting all 15 of its Red Star Rings before unlocking the Red Burst Color Power in Lava Mountain then unlocking the Red Burst Color Power unlocks Silent Forest's Extra level). Each Extra level has 5 Red Star Rings (add that to the 15 Red Star Rings for the main levels of each world, and you get 20 Red Star Rings per world), so multiply that by 6 Red Star Rings and you get 30 Red Star Rings for the Extra levels alone (add that to the 90 Red Star Rings from all 18 main levels that contain them, and you get 120 Red Star Rings across the entire game). Collecting all of the Red Star Rings in the 6 Extra levels (and completing the game) unlocks Lava Mountain's extra level.

Overall, Sonic Lost World 3DS has a lot to accomplish in order to 100% it.

If you are counting the Library, it is 100% Shadow 05. You have to do literally hundreds of playthroughs to truely 100% Shadow '06.
