that is fun to play but no biggie if you make a few mistakes.
If by "no biggie, you mean the sky doesn't fall, of course you are right; but if you mean that you can "get away with" a few mistakes and win, well then you are, ummm "mistaken."
I do understand what you are saying though, usually you do not for example: lose a capital over a trivial error. (But in the case of England and Moscow, the term "trivial" is open to interpretation......[;)])
