Yes, you can create more than one account.
No, there's not an account limitation.

Sure you can play on official rooms with your other accounts then.

Also, you might think it's negative that you get only the tcs for 100 matches per day, but you have to think about the economy. It's not good if there are too many tcs around.

So, as jusmi said, if you really need more tcs after you reached your limit, just try to win some tourneys.

I do believe farming QI is what they're preventing by keeping the game limit.

Also. Toribash doesn't exactly have an economy. There is no limit to the amount of TC you can have, you can buy it or earn it. An economy only exists if there is a limit to the amount of wealth obtainable. In Toribash, if someone wanted to, someone could buy 1,000,000 tc and it would have no effect on the other members. Whereas if 1,000,000 tc was injected into an economy, the value of 1tc would go down. Am I right?
