The theme is what makes the game unique. If the designs were like the ones on the other servers, then of course this game would probably not be implemented as it would be too similar. Also, a microgame has been considered (as Unstitched has said) so as long as the designs and games are different, I'm sure it could be what the developers are looking for.
Party Games is a game where you swap to different games, from what I've read this one you go into different baby blocks and do different games, this is in no way like the major leading networks one.
Again both of you missed my point.
