Like I said why Construct 2 sizes just 59 MB like if we compare with other game engine like game mak master collection sizes around 300 MB and fusion 2.5 developer around 500 MB so c2 uses some kind of compressing techniques??
they don't bundle crosswalk and nw.js, only the html5 exports (release 186.2 and older bundled node webkit and are more than twice as big), that alone must make the size smaller, meanwhile I'd think GM:Studio master collection and Fusion 2.5 must bundle all their home made exporters
Oh I see..
Also C2 has been written from scratch meanwhile the others have, I think, been rewrote based on their previous versions.
Also keep in mind the installer size is lower than the actual size too.
