I just started playing this mobile game yesterday. Its basically Sonic R with Mario Kart items.
You race against people to obtain chests. You need cards to unlock or upgrade characters which come from the chests. Basicaly its race, chests, cards, upgrade characters, race again.
Its fun but out of the 3 Sonic runner games/apps this is the most Pay to Win. You either wait 3-8 hours for chests to unlock or you pay a fuck ton of real life money to open your chests early. So after 4 races your chest slots are full, so its either wait hours, or pay money. Cuz the only reward for racing is chests, so what's the point if my limit is 4.
Its basically designed to feed endlessly back into itself and to get anywhere you need to endlessly pour money into it, Or wait 3-8 hours.
It sucks cuz the 2 mins of racing is actually really fun but everything else sucks.
Sonic Forces Speed Battle, fun game ruined by Pay to Win. Not to mention you are constantly bombarded with video advertisements, you spend more time watching ads then you do racing.
