Unity shares are priced around $40, which would be a fair price to pay for a business generating a FCF/share of about $1.50 per share (using a simple DCF analysis, with assumptions made regarding their future FCF). If you project their phenomenal growth (~20 to 30% per year) in the future, it would take more than a decade for Unity to generate enough profit to be fairly valuated at the current share price. If you believe that Unity is going to outpace this 30% yoy revenue growth, then you can probably get something out of an investment in Unity in the next decade.

On the business operation side, it's very bright for Unity. Building a game engine requires years of development as well as highly-skilled workers. Unity has a strong competitive advantage given: the size of their developer community, the amount of assets available in their store, their great pricing model (free until your generate a certain amount of money), the lack of competition (UE4 and Godot would be the main competitors), the boom in mobile gaming (which is the platform where Unity shines the most).

Regarding the management, we hear from within the game industry that workers are evolving in a constantly changing environment where job security is not at its highest, which can discourage most senior software engineers.$Unity Software Inc.(U)$
