I looked through the nintendo forum rules but did not see angrhing about buying games from other users with forum gold. Is this permitted or am I not allowed to buy games from people with my forum gold like on the steam forum? Any info will be appreciated!

Its not allowed here, only in the donor forums
The only reason its allowed in steam section is because you can gift it to them directly, digitally
Nintendo, xbox, playstation dont have these kind of features, not yet anyways

Thank you for the information!
