I, as a soccer player, play both indoor and outdoor soccer. Both fields have their advantages and disadvantages. I like playing indoor more because the field is more flat and easier to run on. The field also has boards so you can bounce the ball off the boards instead of passing to someone or so the ball doesn't go out of bounds. In indoor the game moves a lot faster and a lot more happens, opposed to outdoor where there is a lot more room and the ball goes out of bounds a lot more. The other thing i don't like about outdoor is the wind can make the ball go in different directions and the game moves a lot slower because there's more room for the ball to go. My favourite thing about outdoor is being outside and when you fall on the grass it doesn't hurt as much. :)
