Hi DarkRikax,
We do not have any plans for a free version of UE4. We think $19 is amazing value. For that $19 you will not receive a watered-down trial edition or feature limited version - it’s full Unreal Engine 4 that we’re using to make our next big game - yet it has lots of cool friendly features, backed by tons of tutorials, content and demos, with more to come!
You spent your $19 and you’re LICENSED to used that version forever; Even if you download engine, use it, and then cancel and never pay again. Also, you can resume your subscription at any time to get latest updates, new features, new content, etc. It’s priced similarly to popular MMOs but can deliver a lifetime of learning and development.
Let me know if you have any questions.
Cheers,
