Because it's a good game, but not as great as people are saying it is. People act as if RE4 is a revolution in gaming or something when it brings nothing, absolutely nothing new to the table. Like this post here:
Shadow of the Colossus is better than RE4. It's much mroe interesting, and has much better replay value. It's also doesn't get BORING AS FUCK halfway through the game like RE4. Another example, GTAIII. I've replayed GTAIII from front to back, beginning to end 5 times this generation. It's most definitely my gotg. RE4 is not as compelling or interesting as GTAIII. A few more examples: SMT: Nocturne, Suikoden III, Psychonauts, Devil May Cry 3..just a few examples in the past few 2-3 years. RE4 doesn't bring anything new but each of those titles listed above are special in their own way. I never got that from RE4. I'm not here to troll but I honsestly just don't understand what is so amazing about RE4 aside from shooting fuckers in the face 2093408 times. I'd LIKE for someone who loves RE4 so much to explain why it's so good to me.
