"If we ever get a version 1.2 in a year or so, it would be nice if we had a Bees Kingdom to explore. Also, an Ant version somewhere else, too! Ants need some major love, too! It is Terraria, after all. And Terraria is just a few letters off from being spelt Terrarium!" - Kind of a lost suggestion I did back then. Memories... We at least got the bees and even spiders, but indeed, still no Ant friends that could even build by themselves! Imagine if they were mob ones that start deconstructing your stuff built only within their main biome, and rebuilt it somewhere else within, or did whatever with it and made more tunnels and walls by using your own blocks as materials for expansion. If their "hills" were a maze, they would be ever changing like that.
But yeah! Happy Birthday! This update was really cool back when I played it year one. The path to each update has been such a great Journey, that the true future final update should just be called "Beyond Journey's End" (if you know what I mean).
