which type you prefer in FPS. carry two weapons or all weapons?

[Barozi]

Killzone 2 actually uses a 1.5 weapon system IMO (which I think sucks a bit. That pistol is almost useless)

Resistance 2 is a dissapointment in this aspect, because you could carry all the cool weapons in RFOM.

Halo 3 features a 2.25-2.5 weapon system (dual weapons & Machine Gun/Plasma Cannon)
