From Oil Tycoon Wiki
Unlimited Mode will take all achievements and technologies and group them by property. It is recommended to complete classic mode before turning on unlimited mode however there is an option in the settings menu to switch over early.
- Gain as many achievements and technologies as you can afford.
- Streamlines the purchase of technology by allowing a long press to "buy maximum."
- All multipliers are averaged out (to between 200x and 150x depending on property), so the excitement of waiting for the x250File:Example.jpg at level 1000 is missing.
- No more titles for achievements and technologies.
