Disney Speedstorm
For many, many years, there has been one GREAT Kart racing game/series, and that was Mario Kart. Now, we potentially have a second one in Disney Speedstorm.
This is a free to play game, that is actually a lot of fun. It has a great cast of characters, the driving is very smooth, the controls are responsive and the music is FANTASTIC. What each power does, is not as obvious as MK, but that's okay.
The only real downside, is it plays like a free to play game. Elements of it remind me of Asphalt Legends 9 (a fun racing mobile game,) because you have to use items to level up your character to make them faster, it has drop boxes, and each race in the "story mode" has 3 quests to complete.
All in all, this is a really good game, and it's up to Disney to make it great. The potential is definitely there.
