From the review:
"'Atlantica' is, arguably, the first high-quality free-to-play MMO. Were there good ones before it? Yes, but before 'Atlantica,' free-to-play almost always meant sub-par compared to retail titles; and if you didn't pay, you were at a distinct disadvantage, or limited in some way. 'Atlantica,' though, changed that. Instead of being 'Lineage Clone #10923,' 'Atlantica' broke the mold, mixing the tactical strategy and MMORPG genres in a new, "Final Fantasy Tactics"-like game."
