The first step in fully appreciating "Star Wars Battlefront II" is to forget everything about the first "Battlefront" game. While both are part of the same bestselling series, "Battlefront II" has been tweaked and refined to the point where it is a fresh and excellent game.
"Archer Maclean's Mercury" is innovative, but cannot compare to the PlayStation Portable's first puzzler, Ubi Soft's "Lumines." Had "Lumines" not been released, "Mercury" would be one of the best puzzle games in recent years, but it simply cannot reach the high standards "Lumines" set for the genre.
