Whee, what fun.

Stupid Spotty stole Hugela and my warp..but we'll get revenge..oh yes we will...

Anyway, Mike, I have some suggestions. ;p

~ Store Upgrades: Every 7-10 sessions of the game, the store gets bigger and runs out of supplies less often.

~ Access to your Room: I wanna go in your room..:P

~ Special of the Day: An item that is not normally sold in the store is sold in the store. There could be only 1-2 of these.

~Sale Day: All the items cost between 5-20 coins less to purchase.

~Grab Bag: If someone buys this, you give them an item of your (EvilMike) choosing.

~Lottery: Each player can pay 10 coins to get a lottery ticket with a number they choose between 0-100. (Limit 5 per player.) Then, one day EvilMike would randomly choose a number (or have someone else that didn't participate choose one) and the closest one would win 50 coins, and if they got it right exactly, they would win 100-150 coins! The coins could also be substituted with rare furniture.

EDIT: More suggestions..
EDIT2: Lotto suggestion ;p
EDIT3: Yeesh, three edits..made it sound better..
