"usually"
about every other arcade game would be filled up decently quickly at all times
(The parkour minigame is the exception though since it was more of a prime time game... games would fill up fast but only at certain times)
Might I also point out that people were quite sad about seeing games like quake craft, super craft bros, Hide n seek (though already broken)
and then there was hour glass
if you look at most of the threads saying that the old arcade games should be added back
you won't explicitly see it being prominently mentioned usually just a "add the arcade games back thing"
and for individual threads? I have not seen 1 thread saying that Hour glass as an individual to be added back (other than this 1)
So it is very clear it wasn't actually that popular
