Due to the design, each confirmation takes 10 minutes. The six confirmations is general, and thus requires 6 x 10 minutes in total.
Not exactly.
First we are talking about in-game transactions, which won't be handled directly by the blockchain, so they would be instant.
Second, the "slowness" we were talking about is that of bitcoind itself (not the protocol), which can be fixed coding.
Ah I see. Never knew that it was possible to also have in-game transactions in parallel to blockchain. Thanks for the clarification!
