The Sonic series is dead...
the voice acting is terrible. When someone inturrepts, they dont even finish their sentence like a normal person would finish one. they would raise their voice into asking a question, and stop talking, followed by the inturruption. Also, when someone says "AH" or "oh no!" they just do not bring any sort of care. Rouge in one seen just goes "ahhhhhhhh..." like she doesnt care, but you would think she would be screaming very loudly. Also, Omega is annoying because every step, or move he makes has a squeak, whine, or clank from his armor. Sometimes, a sond does not even play during a scene.
Now about story The story is lacking interest, and just drags on. And they bring another hedgehog into play, which just makes sonic feel not as original and quite boring, knowing next game theres going to be a "hurricane the hegdehog" or "Rayman the hedgehog". it just ruins the fun.
The story has many bad scenes also, which just dont make sense, and at one time, some cia guy asks rouge for the "book of darkness". its terrible, because it is the scepter of darkness, and she replies to him "no, it broke" or whatever. Also, sonic and a woman fell in love. For christsake!
Gameplay is also at fault. Terrible camera, Terrible control, and terrible glitches ruin it and cause hundreds of random deaths. Times when sonic "speeds up" are highly uncontrollable, and makes incredibly easy deaths. Load times are a burden, 15 seconds each time, and happen at least 4 times a level, while old sonic games would have a trigger in the level that caused whatever was to happen, to happen instantly, and the loads were still shorter. All the bosses and levels are reused for each character, so no new stuff which happens for each person.
Some ups contibuted to the game, like the full cast from all of the other games, and the return of a hub town, along with missions, that though they do take a while to load up, can be fun.
Also, the new character is a blast to control at times, though he may be slow.
With a game like this, it may be hard to pick sonic and his friends up and continue along. Best of luck ( I say this desperately to them) to the makers of the Sonic RPG, please, save sonic.
