I spent most of my time in ZM or Ball Race. Never got into uch much because I always feel I don’t understand the mechanics well enough to play.
On topic though, my biggest worry is that this is super effective. “Well isn’t that a good thing, Arsenic?” Why no, it’s not. That means every day will have a game-mode of the day/hour/whatever the bonus timer is. That means really long wait times to get in the game and a whole lot of empty game worlds since everyone wants their bonus and will be qued up for the bonus mode instead of populating the other areas.
If people are happy with what they’re playing anyways, there is no need to persuade them to try other games. The goal of them enjoying themselves has already been accomplished.
