Everyone has opinions my friend. You don't have to accept them, but you do have to respect them. After all, just simply raising your voice and speaking your mind on a subject like this will bring out the individuals who may or may not share parts or whole of your opinion. Perhaps a majority of the people on this forum do seem to despise FO3 to its damnation. But just remember that if you can't accept someones opinion, at least respect that someone for having an opinion.
As for me, I've relooked FO3 for what it really is and no longer for how I originally viewed it. It's shallow. It's broken. It's too easy. It's bugged-as-fuck. It's repetitive in almost every sense and aspect of gameplay. And most of all, it contradicts and conflicts with too many parts to the canon storyline. And that's a big no no, at least for me.
But I still think that the game is fun. It does hold good replay value if you decide to utilize mods in any favor whatsoever. Hell, you could rewrite the whole storyline if you wanted to through modding, a concept that a lot of people don't seem to see eye to eye with and fail to aquire. Meanwhile, FO3 does make Fallout more interesting in the sense that it experiments with taking a FPS/RPG approach with real time combat. I like it personally. I just wish it was more realistic, like head bobbing or weapon sway and so forth. But Bethesda clearly loves to stay in the shadow of the light when it comes to gameplay improvement (hence when I stated repetitivity).
Anyways, I love FO3 because it's the game that introduced me to Fallout in the first place. It will always hold a special place in my heart, even if it sucks hardcore irradiated mutant cock.
