- Watermark in Build
- Limitation of screen resolution (game resolution)
In an education setting I doubt either of these would provide any incentive at all to purchase the software, so we'd lose loads of sales, and possibly go out of business.
- Limit storage space size for assets
You could probably make the same arguments about why limiting the size of assets restricts teaching uses.
The whole point of the free edition limits is they are meant to be slightly painful so that the incentive is there to purchase a plan, as we need sales to stay in business.
