Both Sonics feel great and smooth and make speedrunning this game really fun. Modern Sonic's style of gameplay is reminiscent of the gameplay in Sonic Colors DS where Sonic can boost, stomp, home in on targets mid-air, and slide. It can be annoying at some times with the homing attack not always locking onto targets when you expect, but overall it makes platforming much easier. Classic Sonic controls just like he did back in the Genesis days, except about halfway through the game, after defeating the two Classic bosses, Classic Sonic can perform the homing attack from Sonic 4. But unlike with Colors DS, there are two different styles of gameplay, being Classic Sonic and Modern Sonic. The format they used for Sonic Generations with the home console and handheld versions is very similar to what they did with Sonic Colors where the home console's gameplay uses the boost formula while the handheld version resembles the Sonic Rush style of gameplay. Score - 2/10 -Gameplay and Controls The gameplay in both versions is why Sonic Generations is considered to be one of the best Modern Sonic Games to date. The story has so little to add to the game, making it very forgettable and almost nonexistent in the 3DS version. Score - 8/10 -Story Unfortunately, this is where Sonic Generations suffers. The only levels I really had a problem with that seemed unfair were Water Palace act two and Radical Highway act two. Almost none of the levels have hazards that can be a pain to avoid, allowing you to just hold right as speed off. my favorite levels in the game are Green Hill Act one, Mushroom Hill Act two, and Tropical Resort act one. The levels themselves are very linear with branching paths which makes them fun to explore and speedrun over and over again. In my personal opinion, the zone selection is even better on the 3DS than the home console versions. Instead of Planet Wisp you have Tropical Resort. Instead of Speed Highway you have Emerald Coast. For example, instead of Chemical Plant, you have Casino Night. The only zone that is kept the same between the two versions is Green Hill, and even then, the levels are very different.
Sonic Generations on the 3DS has a completely different set of levels from the home console version. Score - 5/10 -Level Design OH BOY IT'S GOOD. The camera always feels way too zoomed in on Sonic which prevents you from seeing some oncoming obstacles the first time through the game, but it is not too big of an issue after you memorise the level design While the visuals are not perfect, they look fine for a 3DS title in 2011. Unfortunately, the Classic Sonic stages suffer from the same problem the genesis stages did. All of the models in the game are very low poly versions of the models of the home console's models, but thanks to the 3DS's low-resolution screen, the models in-game appear much more rounded and smooth than they actually are, which is a cool unintentional effect. Visuals Since the game is running on an underpowered handheld, it obviously does not look as pretty as its home console counterpart or even forthcoming 3DS games such as Super Mario 3D Land or Sonic Lost World. Sonic Generations for Nintendo 3DS is a petty good game and, while it is very short with only 6 zones, 2 acts per zone, and seven boss Sonic Generations for Nintendo 3DS is a petty good game and, while it is very short with only 6 zones, 2 acts per zone, and seven boss battles, it alongside its home console counterpart hold the title of being the best modern Sonic Game since Sonic Colors.
