I don't get why people are so mad that the game is actually pay to play, it's one transaction of $5, and you get tons of stuff to do, and it's totally fun, they put lots of information regarding Japan too, so it's not only a game to play but also providing a bit of knowledge regarding Tokyo Japan, if you love Japan and Sonic, it's a mixed between the two with olympic theme on it, gameplay wise there are many range from swimming, sprinting, shooting, climbing, fighting, and many more, so it's totally worth your money, graphically speaking it's on point, try it for 10 stages and if you like it, buy it, there is no harm in supporting a stress-relief game like this, also totally family friendly.
