I "rented" the game last week, and I kind of like it. I wasn't looking forward to the air combat stuff before, but it has actually turned out to be pretty fun. There's not a ton of platforming (2-3 hours in) and what's there isn't difficult. The camera isn't the greatest, since you can only pan side to side and some platforming requires you to look up and down to guage distance. Also, there is at least one section where you have to shoot enemy targets on a shooting range while avoiding shooting friendlies. Ugggh, it doesn't work well on the PSP nub. I like how you can upgrade your weapons/abilities and I could see myseld beating this game if it isn't too repetetive
