It's so nice to win against a strong player if they give up (for example, if they also give you money), why would they forget it, but the result will remain!
Ah, now everything is perfectly clear =)
It's pleasant, of course, to win like this – not by honing your skills, but by relying on luck.
This is the true face of sandbox games.
There should be a desire to become strong, not to receive a concession in something. You need to lose a lot first to start winning – this is true for both poker and Heroes. Patience and hard work will overcome everything.
