Just 2 New Event Ideas that I Think Might Be Cool...
Freeze Tag
It should be a event bot event, not a event house one. 1/3 of the people who join the event will be chosen randomly to be "taggers" while the rest are running away. I'm thinking that the tagging animation should be like the one used in Sumo. Just to make it a little difficult, taggers should have a tiny amount of speed boost. (Tiny amount mind you. Speed boost will not work in this event.) If you get tagged, you are "frozen" on the spot. (Perhaps we should have the animation of your character being frozen like the one in the supermarket below Mafia?) Other players have to try to save you since you only win when your team still remains. (If taggers tag everyone, taggers get money instead.) If you aren't unfrozen within 5 minutes, you are out.
Pacman
People will be spawned in various places in a giant arena. Essentially, it is a giant maze. Like Pacman, there will be items (?) in the maze and you have to collect as many as you can. I'm not sure if I want the items to be picked up manually or like picking up gralats in Classic. In the center, will be a spawning area for NPCs, like the ones in Classic Killers. They will get out of the cage they are in and pretty much chase you until you are dead. You get 3 lives. You will spawn in different areas. Really, it's the admin's choice if they want to allow speed boosts here.
(Sorry if I misspelled anything.) Feel free to edit or comment about my idea.
