Soooo, I see a lot of people like to host events in their house, however they have to find other alternative to match with the ones in actual events like chance.

Perhaps sell some items used to host events? For example a randomized letter/number box. When the owner touches it, a random letter/number pop up? This would be cool to those who wants to host chance.

Maybe add a Trivia item? Like a whiteboard. It can work as a normal whiteboard, or as a trivia item. The owner can write the answer to a question on the board, however it won't show up. Not until someone says the correct answer. The question can be asked out-loud.

Here's an example:

Owner asks question: What's 2+2?
-writes answer on board, but makes it invisible-
-player says the answer-
-the correct answer will pop up on the board-

tbh, I think this is really cool.

Maybe you can buy the spiders you can find around Master Li's Dojo and host that one event where you have to dodge the spider's projectile. Forgot what it's called, but yea. You get the idea.

tl;dr: sell items that we can use to host player-made events  

Yup would be nice  

strangely there are no 'baddy' items or anything that damages you in furniture.

I think it might be because dropping like 3-400 baddies in a house area might cause a disturbance to the game, but I might be wrong?

Certainly baddies and bushes would be nice  

If quantity is the problem, then add a limit?
