My thoughts on Mania: It's everything the fans have been asking for. It's going to suck because it's not want they wanted.
As for Project Sonic 2017, it looks like Sonic Generations 2. This makes me want to get a PS4 faster. Am I the only one who thinks that the level shown in the trailer looks alot like either Rooftop Run from Unleashed or City Escape from Adventure 2?
What I really want this to be (besides Sonic Generations 2) is a game that uses characters from Sonic's past as assistance (the line "even heroes need help" makes me want this). We start with some of the well known characters (Amy, Rouge, Vector) and as you go though the game you get more teammates and by the end you get to have Mighty, Ray, Bean, and maybe even Sticks and Boom Sonic. Like what they did in Generations 1, their can be side-boss battles and they would be agenst hypnotized, recruited, or otherwise tricked characters. I'm thinking Fang/Nack who was payed to be on the team, a reprogrammed Omega, Knuckles who got tricked again, Shadow just to test you, and Silver can be their somewhere (I don't care). As end bosses we can have Eggman, Eggman Nega, either Metal Sonic from Knuckles Chaotix or Metal Overlord, and maybe a new Time Eater/a new dimension traveling villain. If we do get this and we get Boom dimension, I want a mock boss with Boom Eggman that goes into the real boss.
