Do the mobile Sonic games require anything like a consistent internet connection, account setup, etc.? Do they display ads at a rate of one between levels or more?
You need an internet connection to even open the game, and you need a consistent internet connection while playing it. You don’t need to setup any accounts.
There are banner ads at the start screen. They display one skippable or timed ad between a level. They even display video ads AND banner ads in the pause menu.
I got tired of the ads and I wanted it to work offline so I paid for the ad-free version. Sega had the audacity to sneak in an ad button on a paid app. Wtf?
