To be honest, apart from being by the same designer and being tile laying games, the two game are almost nothing alike.
I find that Atlanteon is a solid, quick little two-player abstract. However, the theme has almost nothing to do with the game play.

I have both games, and now I'm "cleaning" my collection and decided to sell Kingdoms instead Atlanteon.
Many people will say that I am crazy... these people only look on the BGG rating and think that Atlanteon has lower BGG score than Kingdoms.
I, fortunately, look other criterions:
- I usually play with my wife (then I don't need a game that scales from 2 to 4 players like Kingdoms).
- I love fast abstract and dry games (Atlanteon is really abstract and dry).
- I don't consider important the art or the theme (in Atlanteon the art is awful and the theme is so pasted -like other great Knizias-). I prefer a good mechanic... and Atlanteon has an OLD mechanic but this works pretty well (IMHO).
- I don't like the maths involved in Kingdoms mechanics and the scoring.
- I like so much the tension on Atlanteon. Sometimes it reminds me so tense game endings like in Battle Line.
- Finally, Atlanteon requires less space on the shelf. This is also a plus for me.
These are my thoughs on keeping Atlanteon over Kingdoms in my collection. Finally I think that Atlanteon is underrated because FF gamers look more for a theme than a mechanic. If you like dry abstracts (Ingenious like games) that could be played fast for 2 players... believe me, Atlanteon is a true gem (specially if you get it cheap)!
