My subject line says it all. Illusion of Gaia takes you on a roaming journey on which you never return to any previous location once you leave the area. The story is charming and becomes increasingly more epic as it unfolds. The action RPG gameplay is pretty fun, and the fact that you can only clear each screen of enemies once (the method for leveling up) keeps the player from over leveling and taking the challenge out of the game. The game is basically linear, with one collection side quest that rewards the player in various ways.
