As the title asks, "Can I setup a lottery in game"? Specific to my guild, thus only members would be able to 'compete' and be able to win a set amount based on the the amount of numbers they have correct ~ The same way lotto works normally.
I have read through terms of service and such and I can't find anything that states this is illegal, but I'd rather ask first before being banned :P
The idea is that X% of purchases would go towards guild hall upgrades, and obviously I won't force members to do it.
PS: I hope this was the correct place to post this question, This seemed the most relevant
