The bold makes it sound like the game is the black sheep of the series that probably won't be revisited. This CoD comparison is weird - does the game feel like an FPS but the shooting is replaced with RPG battles?
Do you know how the Modern Warfare titles in single player are basically a straight line, then cutscene happens, then you move somewhere else, ad infinitum? Yeah, something like that. But instead of some nice shooting you are faced with standard turn-based battles often lasting 2 - 3 minutes each at a time, times one hundred per chapter.
To be fair, a bit like FFX, there are certain plot reasons why you're only going forward most of the time, but backtracking is impossible even late in the game and the places you go through aren't as nearly as interesting.
