I got Sonic The Hedgehog Genesis after seeing the bad reviews, and I disagree with them. The game does have slow downs and a different feel, but I still got some enjoyment out of playing this game. In my opinion, it is an ok game.

I can't understand how this game managed to get released... Worst Sonic game ever! How could Sega and Sonic Team let this disgraceful, horrible excuse for a port see the? light of day? On a scale of 1-10, I give it a 0. Although, on the bright side, I was so outraged by this game that I went on eBay and bought Sonic Jam. Not to mention it got me interested in the series again. But still....

Horrible lag and small screen make this game totally unplayable. Get the original or the mega collection instead.

Absolutely awesome! Sure, it has lag here and there, but the rest is awesome. It actually improved the jump hight!

I didn't find this game so bad. The only thing I found that is bad is that the game is slow at times. Other than the slow parts, I enjoyed Sonic the Hedgehog on Game Boy Advance. I think it's good, but could have been better without the slow parts.

This is why Sega now is a piece of garbage, they are really rushing Sonic games and this is one of them! Sega, how dare you!! How dare you not putting Sonic in the same care that Nintendo did with Mario. Sega, you are nothing more then a company with no heart.

Just terrible. Lag, glitches, and screen size render this game almost unplayable.

A true disappointment if ever there was one. I grew up with the original Sonic game. It was the first Genesis game I ever played. How they could have botched the translation so terribly is beyond me. The addition of the spin dash and the slightly higher jump is cool, but what is with all the lag? The lag makes the whole thing unplayable! Whoever did the port on this one deserves to be fired.

I don't understand why everybody hates this! Sure, it's laggy and glitchy, but I think the save system and Spin Dash are great additions! You should give it a shot, even if you're not a Sonic fan.

The game sucks and should have never be released on the GBA. Next, try to port it on a stronger system. For a 32-bit system with a 16-bit game, I've learned that even 32-bit system can't even handle this crappy port. SEGA, try to port it on a stronger system than the GBA, it seems the GBA can't even handle a Genesis game.

There is only one word that describes this game, "BROKEN".
Almost everything that made the original game a masterpiece is loss in this portable remake.
The physics are a disaster, the lag is unacceptable, the audio is poor quality at best, graphics tend to freak out and act strangely from time to time, resolution is so awkward its next to impossible to see what is going on around you, glitches related to poor programing are quite literally everywhere, the spindash does not even work correctly and there are even a few spelling errors in the sound test menu. The only bonus features are save feature, a level select (you need to unlock each stage manually by reaching it) feature and a sound test feature (unlocked by game completion most likely). Due to absurd amounts of lag and wonky physics, it is incredibly difficult to complete Labyrinth Zone Act 3 and sometimes if you are killed during the boss in this stage you are respawned at a checkpoint stuck underwater with no way to escape but waste your lives on drowning or quitting and returning to the title screen. The game is awful and nobody should waste their hard earned money on this rushed and broken nearly unplayable mess of a game.… Expand

An effortless port that could turn off newcomers faster than the hedgehog himself. Pros: Alright for a quick Sonic run or two; the additional Spin Dash and save system are helpful. Cons: A lot of glitches and slowdowns; unresponsive controls; horrendously redone soundtrack and cheap audio; it's lousy next to ports like Mario and Zelda.

This version of Sonic the Hedgehog is too easy and the controls are terrible. I especially didn't like the new sound effects which removed the feel of Sonic that I liked from the original.
