Bad idea. I don't think anyone will like being "limited" to anything. Ususually people that play hundreds of games at once do it because they can handle it, that guy might have a connection issue.
game limit

Yes, I do not think limits are a good idea either. If a player starts that many games then they may face consequences of losing on time in some games if they are not careful and cannot keep up.

yes, give then some rope etc. but 425 is ridiculous. some people enjoy being ridiculous. you know the difference between adults and children, adults tend to be taller.

If the guy has connection issues is it a good idea to start so many games then? I doubt its a faulty connection. If he played less games he would have a very high rating cos he seems to be a great player, most of his defeats are time outs. Im not for limiting peoples games, just wondering what others thought.
Does anyone think it would be a good idea to limit the number of games a person can play at any one time? Ive just be playing a guy who had 425 games in progress and has over 900 timeouts. Seems fairly ridiculous to me to be involved in so many games. Right now he is in the process of losing literally hundreds of games on time!
