That's a weird argument. Bejeweled and Peggle (two VERY polished games, both made by PopCap games) were blatantly ripped off. (Candy Crush and Papa Pear by King are almost identical ripoffs, save for sprites).

How are the games by PopCap not polished? It irritates me even more that King copies TWO games from the same company... They truly are the new Zynga.
