Non-violent event ideas:
- Hood Decoration competition event. People can vote on the best hoods they visit. Top voted hood gets a nice rare item.
- Gold Charity event - Buy gold for another player and get a chance at a common, uncommon or rare item. Whoever buys the most for other people or maybe the top 100 buyers get a really good stat item.
Mafia Party Event - Throw a party in your hood and invite your mafia members to come. During the party, your businesses would generate extra income, even a chance to generate gold. There would be a mafia party in game chat to talk with your mafia at the party. Going to the party would also refill your energy/stamina.
