Sonic the Hedgehog (06):(Rate:7,50) well what can I say to this game? emmm... well the story for my opinions is ONE of the best stories of all sonic´s games.because the have 3 stories that thet play and the silver story is incredible with a destroyed future,iblis an lava insect jejej,mephiles a cold and sadic hedgehog,the world´s destruction,time travels and more things, and another good thing is the final boss, is the most epic boss in all history of humanity jjeje the idea that can I play with super sonic,super shadow and super silver and the orquestal version of "his world" its super epic and exciting!!! jejej. well and the bad things for me are the 1)the gameplay:because its the same mode of gamplay of Sonic Adventure,but with more grafics and more abilities for example:chaos spear or another chaos powers and the telechinetic powers of silver.and another thing is that eggman its look like an a real person (no animated jej) because the other people (elise and the people of soleanna) also looks like real people jejeje and the worst thing is...is...Blaze the cat dies (or transported to another dimension) buaaaaaaaaa :( its so sadly ohhhh poor blaze I´m love it jejejje.
Sonic rush adventure :(Rate:10!) this is for me the best game of all sonic´s games.well the story its super very excellent with the rencounter of Sonic and Blaze,new character (Marine the raccoon), a new villain (Captain whisker),and the travel for all islands of Blaze´s dimension,and the gameplay its very excellent with the star triks points,new stages,and the vehicles are cool specialy the ocean tornado when attacks with the cannons,machinegun, and flamethrower.
Sonic riders zero gravity : (Rate:9,50) well the story its very excellent and tell more things of babylon garden and the babylon rouge,and the arc of the cosmos are very cool esparsed for all the world. and the gameplay its so cool with the zero gravity of drift and turbo, the gear changes like air machine or motorcycle,and new extreme gears like the wheel,rollers,yacht and other news.ohh another good thing its the survival mode with throw missiles,and the game of ball.
