Agree with the above in the main.
Games major content is updated quite slowly though they are pushing crossplay and connectivity between platforms heavily.
I'd estimate 65% content wise so a way to go yet.. that said. The content we do have is good with a fair degree of replay ability as the multitude of variation play (Speed Run pacifist run Hardcore run etc) videos show
Its certainly worth the current price - even when not on sale, as it now stands a refinement tweak patch is on the public test branch as we speak which I imagine with go live in a week-ten days if they follow the usual pattern.
on balance defo try it while its EA cheap.
