Would you think that it is a good experience for players to play while there is snow, rain or hall. of course, they fall and stuff but the game is more entertaining.

why not? There should be game held inside the volcano!

No

Nah I wouldn't risk the health of my players. 

i remember when i used to, and i was like 13 at the time! 

no way its entertaining

Playing football when it's raining is fun you get to fall down a lot it tests your balance

when there's no snow on the pitch it's okay but when there's huge amount of snow it's almost impossible to pass it when u want. 
and about rain, I really like playing when it raining, more rain = more fun.
playing in hall? yes! here u improve a lot of technique.

Players get ill and its not very healthy.. Footballers need to rest to get some energy and stamina for the upcoming match..

had practice last year in -18 Celcius. and yes my toes went blue. Couldnt feel anything after 10 minutes and the prectice went on for 1 hour longer

Watching people play in rain is fun. But actually playing in a flooded field is frustrating as all hell. Passes never work out right and the field stops the ball.
