Always take reviews with a grain of salt, because this has got to be one of the most addicting games on the PSP ever.
First off, this game is not for the casual player. It takes time and effort to even learn this game, but it's very rewarding. Merely knowing which weapon is right for yourself is a task, but it is a task worth doing. Secondly, the camera controls plus lack of lock-on is may turn off others, but in reality, those who mastered the MHF series will tell you "Lock-on is sacrilege. The accuracy of your hits matter." Games like Phantasy Star have a loose lock-on and a full lock-on function. However, that makes it horribly easy.
The game features a myriad of weapons to choose from, all with their strengths and weaknesses. However, greatswords and hammers reign supreme on Blademasters, and Heavy Bowgun on Gunners. The game also has a friendly-fire system, in which you will actually get hit by your ally's attacks, making party play that much more tactical in terms of approach and weapon selections.
The lack of online is really no problem, as there is XLink Kai. You do have to invest in a wireless adapter + router, but it's worth it, both on MHFU and MHF2G.
