IS there an upgrade availble from CM10 to CM11? I know the download's only $20 US, but i figured a few $ is a few $, and no harm in asking . . .

Sorry, there's no upgrade available.

At least it's half price now... when Chessmaster Grandmaster Edition was first released, it was $40 USD.

In the past, a rebate was offered to those who had the previous version of Chessmaster. It's a pity Ubisoft didn't do that with CM11.

TY for the quick reply.

Just a note that in the UK at least, CM11 is now a mere 6.45 pounds ($10.64) at Amazon UK at the moment and I'm just about to order it at the price (I bought CM10 quite a while ago and I don't think CM11 is much of an advance from CM10, hence I've been waiting for a big drop in price before diving in with CM11). Sadly, Amazon US are charging almost twice as much ($19.55 - a pitiful 44 cents off the US RRP!).
