I knew about these and I've been looking at them for a while. I still don't have Team Sonic Racing or Sonic Forces although I soon I'll be receiving Sonic Forces with the joycon skin bonus.
I love multipak releases (not compilations, though I like those too, but specifically re-releases of games from the same console, repackaged into one release) so these are right up my alley. I'm just curious what size cart they used here, since for Team Sonic Racing SEGA said they didn't include the opening video because it would have forced them to use a more expensive cart. Maybe Sonic Mana + TSR fit on the cheapest 8GB cart easily and it doesn't matter?
Also I'm wondering if Sonic Mania includes the DLC or not.
