Why is this any different than Flash preloaders just a moment ago? And even worse - it doesn't show any progress so there isn't any user feedback. Every (bad) pattern seems to repeat itself. Just using current-cool-tech. I would much more appreciate that dev time would be put into a framework that allows graceful enchancement by deferring loading more heavy components and to allow user to interact with the site ASAP.…
Yeah, because I really want people to interact with my game before everything is fully loaded. Great idea.
Rightfully getting downvoted but I still believe my argument is valid: there are certainly use cases for these kind of loading screens.
