I could compare this game to Sonic 2 in terms of originality, creativity, and all the fun points and they would pretty much be equal. I loved both games and this would bring all of the points of the old games and showed them a newer light. I enjoyed this game on the DC (the GC one has nothing special, like SA2B...) and progressed until I would have nothing to do but no, there was the Chao world. Even though the SA1 Chao world wasn't as good as its successors, it was a great intro for these Tamogatchi based pets. The boss battles for Sonic were so generic I couldn't believe other 3D games didn't follow, e.g., Sonic first battle with Eggman showed the classic simple showdown. In many battles against Chaos, a new slimy opponent, we can witness its eveolution which makes eveything tougher. Put the bad voice actions, Big's sad fishing, and a few glitched away and we have a perfect game for the DC. For ten dollars you can buy this, and it is much more valuable then you may think.
