Yeah, MHGU is content rich as well. Though I don't know how it compares to other games in the series. (I enjoyed World and kinda hated Rise.) 

Most comments I'm reading about the game (via Reddit thread, "if its worth buying") say yes. For its sheer amount of stuff to do/hours you can put into it. Though it does come with a lot of caveats. So it'll depend on how little graphics matter, and if you can accept simple level design and more clunky/'old school' controls.

The online is apparently less populated than Rise. But it's still fairly active. [i]According to the threads I've looked at.[/i] (Plus, if its on sale. You might get an influx of new players.)
