(sorry for the poor english, I wasn’t born niether on the united states or the UK)
I like Bad Piggies on iPhone. 
If you research with these terms in the forums you will find numerous threads about this topic. Very recently , actually
this would have been faster to try

the room 12 are very high quality!
the light box is pretty cool 
Hearthstone from blizzard is obviously at the top
successful and high quality i would say
Maybe you should just look at the thread on this in the showcase forum

Rochard was a fantastic release.
Graphically, I like Dead Trigger series, Shadowgun series and The Drowning on iOS.
On PC, I like Gone Home.
It looks like RUST is doing VERY WELL - currently the top-selling game on Steam, outperforming DayZ and heavily discounted copies of Saints Row IV and Company of Heroes 2; with more than 605,000 copies sold netting them over $12.1 million since the early December release.
It looks like Survival game will now be the next Slender! 
BTW, Rust is also made in Unity. There is another Unity success story right there.
Another one I can remember - CSR Racing - made over $12 million PER MONTH in revenue, so made in Unity.

Those figures make me sob :roll:
Two things come to mind:
Get your **** out there, stop wasting time
Obviously graphics don’t mean that much
In my opinion KSP is best unity game.

Right now, three of the ten new releases on Steam are Unity games. Well three that I know for sure: Paper Sorcerer; Might and Magic X; and Blackguards… all RPGs strangely.
