Red/Yellow cards for soccer.
 

I could use yellow and red cards for soccer, would make it a bit more fun.

And perhaps give them the ability to kick people on the field?

do you mean the ability to kick people?
or the abiliy to kick people off?

The use of yellow and red cards sounds fun, maye we can make it so that ppl get a yellow mark above the head and when they've got the red one they are not able to enter the field again.

Yes. He's right tho, you should give us players the foul ability, or there'd be little use for the cards :p

What about if when you go to slide tackle the ball there is a 10% chance you knock the person over. If that happens its a foul.

Yeah, thats pretty good Fayt.

Or, if they just miss the ball and hit the player, it's a foul. Simple. Now let's start talking about including offsides. Haha nah jk.

offsides will be funny to do lol.

I've had to host games where people get on the field who shouldn't be. Red cards would be a nice way to take care of that, rather than sending folks to pillory.

That's what I thought, and after each goal I make sure everybodies ready, and anyone that starts before I blow my whistle I'd give a yellow. I didn't really want to give yellows and such for tackling since it's near impossible to see with everybody runing around. But yes as Sam said, a way to kick people off the field.
