this be probably one of the best sonic game i have ever play . i can tell you right now that this unlike almost all sonic the hedgehog game for various reason . first off and this game be not really mean for kid for various different reason . for starter and some of the comment make in the game be not one i would think young kid would understand . also and the plot be very complicate for young kid . another thing and rouge the bat tear away from all sonic game and make it very obvious that the creator have intend it to be for fan now who be fan from the very begining . some of the big fan be from 15 25 and so that where i be guess rouge come from . rouge be a sexy and sassy . . bat that use looks and more to get her way . not only that and but a costume she aquires later be a very . . showy costume . i also must say that the end game be most likely not mean for kid . let put it this way and so i do not give anything away and dr. gerald robotnik make his little speech and then people in the background start scream thing that would familiar to older audience . anyway and enough with why the game be not really mean for kid . let move onto the good addition to the game . i must say and i be really impressed with the graphic in this game . everything be full of detail and down the very last leaf on a tree . in fact and most of the game be almost in completely render 3 d. unfortunately and there weren not a many cool cut scene like sonic adventure have with perfect and realistic animation . another great thing about this game be the music . every character level have the same type of music and that be very well organize . sonic get regular rock music and tail get some sort of hippie music and knuckle get really great hip hop music and shadow get total techno feed music and eggman get techno mixed in with heavy metal and and rouge get very catchy jazz music . i must say that rouge music be so catchy that i walk around hum her music . another great addition to this game be the character shadow and rouge and which be awesome character . i really hope that shadow end up get his own video game series after this . rouge be great and but she could have be well . sure she could hunt good than knuckle and run fast than sonic and but be a bat and she still couldn not walk on ceiling or use any supersonic wave that bat would use . plus and a glitch about the game and be that she fly in cut scene and yet she can only glide when you play a her . however and she be a great addition to the game and and i would love to see her come back . well and in general and sonic adventure 2 be probably one of the best game i have play in a long time and and i look forward to sonic adventure 3 on the gamecube by nintendo .
