So let's look at the Pros and Cons of Ep.2 as of now.
New Physics (Uncurling, Momentum based Inertia,)
Red Rings indicate more exploration within levels, alternate paths, and what not
Btw Red Rings means new collectibles
Online + Offline Co-op
Game has major originality compared to Ep.1 (Sylvannia Castle Zone and White Park Zone show this.)
Level gimmicks so far (digging through snow, using Tails to guide you through water, having him help you fly) look fun
Badniks and (from Concept) Bosses look cool
More Plot/Story driven then Ep.1
Still unsure about Physics (People say the trailer makes them look bad, others say the trailer makes them look great, have to wait for more gameplay footage to tell)
Level Design looks Dimpish, (Boosters, Springs, Boosters, Springs, noticed alot of Bottomless Pits in White Park Zone.)
Tails is only playable in Co-op, which is SUCKS MAJOR BALLS. (Though interestingly enough, someone pointed out how cool it could be if it worked like Advance 3 where Tails and Sonic could switch to be the leader. Very Unlikely though.)
Pros still outweigh the cons, though the importance of the Cons can make or break the game as well. Should people be saying this game sucks after one trailer? no. Generations gameplay trailer, people said Modern's levels would be linear as Classics's would be horrible, yet they were wrong. Same with Colors. Can't judge a game by one trailer. Though this isn't going to be one of those "Well wait till you play the game, well wait till you beat the game, well wait-" No, we should be able to tell if this game is fun or not by either alot of gameplay footage of someone good playing the game, or a demo (which Ken said would come.)
Ken, btw, that was a horrible and lazy excuse to say. "Well if we made the physics 1:1, then it would break the level design" Does Dimps not understand something? THE ENGINE OF THE GAME IS ONE OF THE FIRST THINGS YOU MAKE IN A GAME, that excuse informs me that not only did Dimps not bother to make them 1:1, but that they could've but didn;t bother. The latter screams laziness and once again makes me wonder, why the fuck isn't Sonic Team (the people who brought us Colors and Gens) not working on the sequel to arguably their best game? Makes me confused and angry at the same time sadly.
People saying "I've lost hope, I've given up on this being good, This is a piece of turd!" Are overeacting to 1 minute of over edited footage. And the others saying "You guys are idiots for saying this will suck, This game doesn't suck, you do!" are just overeacting to the overeactions of the game.
This is not the Sonic 4 discussion as I truly imagined it.
