You're missing out too - and I say this as someone who used to only play DF. DF is amazing, but there are tons of other games that are just as amazing or nearly so (Minecraft, Fallout, Terraria, Portal, Spacechem ... dear deity, Spacechem. If you buy one game this year, buy it). None of them really compare to DF in learning curve or sheer complexity, but they're all really good.
