I see that there are about 20-30 Mods of every game at Voobly. And the Modders make New change of these mods, every month...

I like to play a CHESS. So I know the stats of the units. I may play CHESS now and come back to play CHESS after 1 or 2 months. The game will be the same.

But at Voobly, the games are different every week, similar to Online game. At Voobly, I need to learn the NEW stats of the units, every month... I DON'T like that. For Example, I play Aoe 2 Conquerors. If I play at other sites, the game is always the same. The RULES are always the same. But, if I want to win a game at Voobly, I must learn the game constantly and continuously. Is is NOT fun. I may learn a game constantly only for money.

Remember that the rules at other games are NOT changed for 20-50 years- tennis, football. And the best players begin to play that game only for fun.
