i used to just sit at tycoons for hours, i would ALWAYS have to get all the upgrades.
Believe it or not, my friend and I actually came up with the concept of a tycoon in Roblox. He scripted it, I sold admin t-shirts and we both hit it big. He released the tycoon elements and people took over. Really, it rocked. :D
It was before GUIS.
So was mine, but I never knew if it was even possible. Someone actually made a machine that could do that, it was awesome, but I always thought that GUIs might just make the process possible due to it's simplicity.
I like GUIs but I hate the fact they made the entire in-game interface to use the GUIs.
