By unpopular, it means the games were not filling up fast and it the people who liked it were outnumbered by the people who did not. If this was to get added back, it would only be on the features games list so it would have a chance of showing up as a featured game every once in a while.
And what about hunger games? I don't see a lot of people playing that but it's still there. Games that I've always been in never fill up fast. That makes no sense to me.
Money walls was removed a long time ago so it wasn't included in the featured games list as the code was not up to date. Survival games was also not popular yes, but it was removed later so it could be easily slotted in with others. If the demand is there and the devs can salvage the code, money walls can be added as a featured game.
