I forgot to explained as you asking in your question too. But Sonic 3 and Knuckle feel like very good successful sequel if you enjoyed Sonic 2 or CD. i can say the same stories for the Rush series but i do believe there a minority enjoyed this game, here at SSMB. so its totally different opinions. What really turn me with rush games was the fast paste when it come to gameplay mobility, kinda like Advance 3. But the boost did indeed help-out. if you enjoyed Rush play and multiplayer. Rush Adventure did have online Vs. and my mind, this was very actually fun!
