From one of my projects (a MMORPG) I've learned that the required accuracy in non-financial transactions is often underestimated, while, on the other hand, financial transactions are often less critical that initially assumed. After all, compensation in financial transactions is often straightforward to calculate and apply. But the damage done through dropped/failed non-financial transactions is often hard to assess, and it's also more involved to find appropriate compensation.
