If you played MHF2, you'd notice a big change; the graphics are much clearer and the fact that there's no lock-on is what distinguishes those who like it and don't like it normally. I for one, like the fact that there's no lock-on because it requires skill and not just button mashing. The loading times from MHF to MHF2 are also shortened and everything has been more refined and organized. Also debateable between fans of those who like it and don't would be the length you put in to it. You can't like the game if you don't invest at least 10 hours in it.

I have over 500+ hours in the game and it's still addicting. It's especially fun multiplayer and most people who play for an hour or two aren't far enough in the game to realize much about it. In Monster Hunter Freedom 2 for example, you have to get past the Yian Kut Ku (which is basically a wall for people because it's the first time people realize that they have to be able to recognize attacks and use timing to hit things instead of running up and smacking monsters to death.) I'd try out MHF2 to see if you'd like the game (I found mine for $5 in a bargain bin) and then upgrade if you like it since the data transfers over.

If you're one of those people who play games as far as they can if they look interesting just because you can, you'd enjoy it. If you're the type who says the first ten minutes don't interest me, screw this, then this game is not for you.

You'll need patience.
And friends. :D

I've got over 500+ hours in MHF2 and over 100 in MHF1. I don't bother with Gamespot's overall scores anymores and use player's reviews as a more accurate representation. The main thing I like about the series is all the quests are ridiculously long so when you kill something, you feel as if you've earned the kill. The only improvement they could do is more items, more monsters and/or a more engaging storyline. That might seem pretty picky, but I'm more then content with everything I've done. The games have been worth their 30 dollar price tag (and 10 dollar price tag; MHF2 was in a bargain bin and still new in the case :D ). I look forward to the next one.
