Achievements in Game, but not on steam?

I have played all the sims games over the years,  from when it was Maxis to these days where the Sims 4 free to play! It did however take me a while to play the sims 4 for one silly tiny reason. 

I like 'complete' stuff, to have a goal in mind when I start a sandbox type game. Whilst I've enjoyed about 30 hours of gameplay building my real life house and family and building it up until we're millionaires in a mansion version of my property. I kind of got bored and didn't really know what else to explore.

With many other games, once i've tired of the original gameplay, I got into completion mode, I explore the game via the way of achievements. I noticed the other day that the game has acheivements and these may well be tied to Origin, but they are not tied to steam.

I personally think I would spend a lot more time in game and possibly on DLC if I had more of a reason to. 

I would love to see the achievement added to steam, it'd also give the chance for people to display more from the Sims on the Steam profiles.
