I'm honestly not that much of a gamer anymore. It's like I got "gamers block" or something. For example, I was eager to get Sonic CrossWorld and Rumble, but I still yet to play it.
Take your time, they're not going anywhere.
CrossWorlds at least,
dunno about Rumble next year but right now at least in mobile it's still SEGA's top downloaded mobile game.

but if you can't skip it, then that's just bad game designing?
If we can't skip it then it's not side quest anymore, it's becoming part of the main mission.
