Dragon Kick Your Ass Into the Milkyway, Capcon has mastered the ps2
The two best games for the ps2 are: Resident Evil 4 and you guested it, God Hand. Both games by the one and only, capcon.
Lets start this off with that there is no introduction to the game at all, but who cares ! this game isn't about plot its about kicking demons asses and thats what this game delivers better than Onimusha ( another capcon ps2 greatest )
i relate God Hand to onimusha because onimusha was the best beat em all until GH came out. Anyways the fighting in this game is great because you get to choose what moves you use while u unlock them or buy them in the shop. Where you can test them out after on a training simulator which is a funny woodden dummy that comes to life, and also a challenging arena which loads of different and difficult battles where after you earn money to buy more moves and complete more and more fights in the arena. You also have whats called the Roulette which is an asortment of awsome special moves u can prefrom once you collect enough orbs ( My favourite, Kung Fu Tango :P!!! ).
Now for the audio, which is the best part of the game i find. There are enough hilarious battle cries coming out of the eniemies mouths that it just makes u want to kick their ass ( my favourite "Im brutal and ruthless", its alot funnier in the game). The music is also very well done, catchy and good to fight to. and last the graphics are as good as they're gonna get on the ps2.
I would definetly recomend not only renting this but buying it because once you beat it u'll definetly won't be bored with it yet.
