Ah ha! Yes, the scripting bit is where it would be challenging for me since I've only used blueprint before. Time to switch into Unity then. Anyway, your links for learning stuff are very helpful, thank you!
I wouldn't necessarily jump to unity. I've used both a fair bit but am still in the beginner zone, and I think unreal is much more beginner/artist friendly. Namely because of blueprints integration with the engine. Unity does seem like the go-to choice for mobile and 2d games though that's not an area I know anything…
