Looks like Unreal aren't alone in awesome new licencing terms -- Unity 5 now includes all engine features in the free Personal Edition, royalty free.
For Unity 5 Personal EditionMay not be licensed or used by a commercial entity with annual gross revenues (based on prior fiscal year) in excess of US$100,000, or by an educational, academic, non-profit or government entity with a total annual budget for the entire entity (based on prior fiscal year) in excess of US$100,000.
The Personal Edition still contains a splash screen, and looks like it may not include deployment to additional platforms -- although it does include all currently supported platforms.
