Since this is just a collection of old games that a bunch of people have played before, I won't talk about the actual game play except that it's very fun, very short, but better with all 4, well 6, classic sonic games, and it's SLIGHTLY the same thing as the genisis versions. ( more on that lter on in the reveiw)
So the Collection includes Sonic the HedgeHog, Sonic 2, Sonic 3, Sonic and Knuckles, and what I was really impresed about was the improved versions Knuckles in Sonic 2 and Sonic 3 and Knuckles.
The improved versions are really the same game but with Kuckles in them, but Sonic 3 and Kuckles is the best game out of the collection ( based on content) because it combines Snic 3 and Sonic and Knuckles, with more stuff added like Tails and the master emeralds.
The collection isn't the most refreshing thing in the world, but it's nice becase you can use touch contolrs to pause it WHENEVER you want to pause the game, and you can use buttons or touch to selest the game you want to play from the collection.
But some things are missing. You can;t airlift Sonic with Tails, and you can't use some of the cheat codes to reisit Certain levels.
Out of all 6 games this collection has to offer, Knuckles in sonic 2 is my fave because Sonic 2 is the best out of the 4 standard games, but with KNUCKLES, my fav chracter, it's twice the awsome. Sur he's slower than Sonic, but his glide and wall clime abilty sur make up for that.
If you've never played Soni and you were confused by this reveiw, pleas check out this youtube channel: http://www.youtube.com/user/ClementJ642
Over all, as a collection, it was alright. It didn't add any new unlockables, but there was some bonus art in it. But luckly this was a collection of Sonic, the funnest and fastest platformers around. And in the end, that's what a collection should do. Provide/include multible exillent games in one for a cheaper price than sepratly. 4 (or 6) is difenitly better than one sonic in this must have Sonic collection.
