This game is living proof that Sega still cares about Sonic. It took them long enough, but they realized what they were doing, and this compilation of some of the best zones ever is the perfect peace agreement. Here's why in two words.
Until you play this game, you have no idea how awesome it feels to see the Sonic you knew and loved from the 90s skateboarding down City Escape Zone trying to avoid a speeding semi of death. This game has SOLID gameplay that has clearly been dramatically improved on Modern Sonic's side with an upgraded and tweaked moveset. The game does suffer from one thing that Sega just keeps doing no matter how much they improve...side missions.
While the main game itself is quite enjoyable, if not the best thing that's happened in the entire franchise, the challenges are quite annoying. I don't know what kind of awkward Sonic fan actually enjoys doing these missions, because they know how to make you hate the game, and hate it HARD. It is with a heavy heart to say that you will need to do some of these really tough challenges to buy some skills in the game, namely the Boost Gauge Upgrades and Shields. Even worse, the game makes you do them anyway, because how else are you going to get the keys!?
Aside from that and the surprisingly lackluster Casino Night Zone DLC, and I use the term "DLC" very charitably in this game's case, this game is adequately challenging and very fun to play. In fact, these S ranks are probably the easiest you'll ever get, so if you're a fan of getting the game's satisfaction by being a straight-up masochist, your job is now made easier and less painful.
As for the story...ugh...let's just say I wish the Colors writers never existed. Ever. They apparently lost their luster when they tried to be funny in this game.
Other than that sour little notion, this game is more than worth your time, because this shows that Sega does in fact remember Sonic the Hedgehog, and quite well.
This is a love or hate relationship. Sega took the best stages (or what they think) of the multiple sonic titles and combined them into one prepacked deal, pretty cool the music and the game play are cool great visuals my problem comes in with the controls they suck when you really need to perform a certain action its like a hit or miss with a game like sonic the controls need to be as responsive a possible no exception, but in all its a fun and frustrating game.
