Lotto.
I suggest introducing a script of a lottery system.
This would include buying a ticket ingame, whether it be in a 24/7, supa save, or just walking around/driving ingame using the menus or /lotto (Lotto number) .
You will then pick a number between (1-100). If you are picked... you could win $100,000 to a maximum of $5,000,000.
I know there's a few server that do this. But its another feature we could use.
Let me know what you think,
