am... I see ubuntu?) It's nice news, because I plan throw away win7 or win8 and switch to linux OS)
About filesize I agree! Yesterday I get Unity5 and create simple scene with rotating/scaling cube. In standalone *.exe file it took around 20mb! In web player based (html page+some java+unity file) it took around 300kb. (WebGL took around 200mb file, don't know why, and don't run at all)
Today will plan compare UnrealEngine 4.7 with simple scene. Standalone and webGL
Yep. Simple things require too many mouse clicks . Have you tried Blackmagic Fusion? It's worth having a closer look. The free version offers 99% of features available in the paid one. Fusion is pretty artist-friendly and offers a whole lot of motion graphics tools.
