The bombs ended up being about 45% of revenue, so I think that financially that's a "success". Of course the total revenue is still not great, but I think that has more to do with the overall appeal and/or visibility of the game than saying that bombs failed. But yes, the bombs still bother me from an ethical point of view. I think freemium / consumable IAPs can work, in a way that leaves players feeling like it was worth their money. However I don't think they really suit the 'gameplay' of ZOS (it's not even really a game - more of a toy). A while ago I read this article, which talks about the risks of optimizing for short-term revenue at the expense of increasing player churn and ultimately losing out in the long term: http://www.gamasutra.com/view/feature/188197/the_metrics_arent_the_message.php http://www.gamasutra.com/view/feature/188197/the_metrics_are... In the next update for ZOS I'm planning to make the bombs free. I think they were an interesting experiment - they earned a bit of money and were an interesting learning experience. However ultimately I've learned that IAPs don't make sense for the type of game that ZOS is.
