Heard the playtime is a little on the short side. Maybe I contradict myself here, but seeing the higher price for a Switch Retail-Game with about 4-6 hours playtime will definitely hurt my wallet. We all know there is no need to charge 10 Bucks more for Switch games in boxed versions. So, if there will ever be a boxed version of Sonic Mania, the Switch Version will definitely not be my first choice. I couldn't resist by the way and purchased it via the eShop, since there were 5 dusty Bucks on my eShop Account left.
I'm disappointed that there will be no DLC. This is one of the few example a DLC could be very neat. Yes, I'm an Amy Fanboy (in my case, Fangirl). Additional Characters are awesome when I look back at Inti Creates Blaster Master Zero and Mighty Gunvolt Burst.
I actually would love to see new story campaigns. So much potential here. I really appreciate their decision in an day and age where a century old game like Dear or Alive 5 is getting it's 7th Season Pass. But here, I see a wasted opportunity.
Really hope they will continue this Sonic revival and I wouldn't mind a few DLC. There are very few games who can profit from DLC content.
