Overall: 5.5
Sonic 3D. One of the first 3D sonic games made back in 1996, sort of. I don't really like this game at all, well the Mega Drive port, the Saturn's one better overall. With the game having a isometric view, giving a 3D look. When the game first released a lot of people where amaze, Sonic in 3D this is a sight to be hold. Well the games was played and it looks horrible. Also to add, what is sonic know for? Speed right?. Well in this game he jogs.

Graphics: 6
For the time the game looks good and has good animation. Sonic look like Sonic in 3D. The game is colourful and that's all it got for it. But the game world looks nice in the background and Eggman looks like an egg. The shadows can be hard to judge where the platform is and you can make a jump and swear you made the jump and find out you didn't.

Sound: 7
The soundtrack is good and the level music sounds great and some are better than the Saturn music. You can tell it's sonic music when you first hear it. However if you get stuck on a level, some of songs will get very annoying and you will want to stop playing. Some of the soundtracks where remixed and put into Sonic Adventure. Some soundtracks are good but some are just boring and don't suit the level. , the Volcano Valley is a good example, the music suit the level really well, while Spring Stadiums level music is horrible.

Addictiveness: 2
the game is not repayable at all. The only reason is that you collect Flickes and put them into a big ring, and do that over and over again. Being the Flicky savior can get boring after about 6 times. There no change like the number of Flickes its always 5 and you need  to save all 5. The game good for Nostalgic reasons, but for a time to relax, no.

Story: 4
The story is that Eggman has kidnapped all the Flickes and has used them to build his machines and Sonic must save them by putting them into the big rings, and that's it for story. The chaos emerald's have no purpose, unless you want a good ending. Its a Sonic story there wouldn't be much.

Depth: 3
Well the depth is poor apart from that there 2 special stages in each level via Tails and Knuckles and that's it the game go not depth at all.

Difficulty: 3
The game is not that hard, unless your in Volcano Valley and with no fire shield, then you will pull your hair out in rage. The rest of the game is easy. The bosses need no guessing you know when its time to hit them. The controls are hard as using a d-pad to control a 3D game is hard. But if have the Sonic Mega Collection or the Mega Drive Ultimate Collection (Genesis the U.S) then the controls are better as the analog stick make Sonic easier to control. The special stages are very easy. Collect 50 rings, then 100 and then 150. Sometimes I've collect 150 rings before I needed to get 150 rings, it that easy. 

Sonic 3D is not that great of a game. The classic ones are much better and music is good but avoid the Mega Drive version, the other versions are better overall. Apart from the Saturn, the load time are worst than Sonic 06 but that's the only issue. The PC port is the best so try and get that one if you can.
