This game is absolutaly amazing, I bought it because my friends have it, and I play it so much I am just as good as them now, I've bought games since I bought this one but I still play it and it's my favourite game, ever... It can keep anyone(interested in gaming)occupied for hours and hours, days and days, weeks and weeks, months and months.
The graphics are not as good as I explained the game, because you walk through some things, but it does not mean the game has bad enough graphics to stop playing it, don't let the graphics put you off... Even though they aren't too bad anyway. Good enough graphics to play and enjoy, definately.
The sounds are pretty realistic, you wouldn't expect some one to fight a big dragon thing without shouting or screaming a bit, but the game makes all the sounds that anyone would need to hear, sometimes I put my PSP on mute because the sounds are so good that it's anoying. Hehe
Even though there is only a few different maps to play in, the creatures don't start in the same place every time you play there, so it is always a challenge to find and kill them, The variety of monsters you can anihalate (sorry for the spelling) is amazing, you kill from big rock things to mutated fish things.
As frosties would say... It's grrrrrrrrrrrrrrrrrrrrreat.
I might have allready said this alot but this game keeps you entertained for ages, me and my friends have all got over 200 hours play time it's so good. If I were you, I would buy this game straight away, otherwise when like monster hunter freedom 5 comes out (dont know if they are going to make one) you will still be playing number 1.
All in all... Graphics are great, keeps you happy for ages, sound is great, this game is just so good I would need to have alot of room to tell you how good it is. So I will round it up by saying that you would be stupid not to buy and enjoy this game, I will be playing it for a long time to come, thanks for reading.
