I watched this video by the youtuber Chaomix and thought it was interesting enough to start a thread about. It's essentially the age old question of "are 2D Sonics unfair since you don't have enough time to react to oncoming threats?" there are three main points in the video: 2D Sonic can sometimes be unfair due to threats that don't allow enough reaction time 3D Sonic kind of fixes the problem by laying everything out in front of you. "[3D Sonic] is less reaction and memorization based and more decision and execution based". A way to solve the 2D problem could be by making Sonic's sprite smaller and/or zooming the screen out to allow more to be seen. Not sure if I agree with everything in the video but I definitely recommend watching it. It's not very long, there's a sponsor at the start and the video starts properly around 3 minutes in. I'm always interested in exploring the ways that 2D Sonic gameplay can advance and improve. I think a perfect 2D Sonic game that appeals to new and old doesn't exist because it simply just hasn't been made yet, but definitely can be done. Would love to know what everyone's thoughts are.
