I am not entirely certain. I've played through almost the entire single player WFC campaign. I had fun, but when I replay through on another difficulty setting I will get a sense of the pleasure of replay value. So far I've felt that ROTF had great single player replay value. And I'm an old school gamer who values single player mode over multiplayer always. The graphics of WFC are excellent, the controls solid and the themes (G1 inspired) are nearly perfect. However, I find the linear, almost Super Mario Bros style of platforming from position A to B to C somewhat too simplistic in nature. The graphics of ROTF are decent, the controls are great for me (though I know lots of people hated those controls and responsiveness) and the themes are good enough as they were completely in line with the source material. I wish you didn't have to hold the button down to stay in ALT mode, that drives me crazy. Bascially I found ROTF a bit more creative in terms of what the mission objectives are. WFC is a shoot, shoot and then shoot some more shoot-em-up shooter. In ROTF there were missions where you'd have to shut some transmitters down, track down humans and deliver them elsewhere, defend positions, activate things, acquire objects, escort missions, etc. etc. etc. While WFC was more of a triumph with the old school G1 designs I can't help but wonder if the replay value would be upped with more dynamic mission objectives besides "shoot everything that moves." I have yet to experience multiplayer but what I've read it sounds like some pretty simple objectives. Thoughts?
