The stages are big, and very tedious if you're not the patient type.
Not only is the map size a little too epic for a comfortable play, the dense jungle set design and the enemies dressed in green makes everything an eye-strain. There can be a lot of tactical decisions for most of the setups, but for me, it ultimately boils down to clearing the map for a sure-win way to complete the stage. Due to good A.I. and incredibly realistic mission setups, it will take a lot of time to clear each stage trying out the various tactics the previous Ghost Recon games have taught you. The gameplay in Island Thunder is one of the most challenging in the trilogy, and if you've already played the first two games, there's no reason to give this one up.
