I''ve seen some action games with an "arcade mode" and a "PC mode" of gameplay. I''m not totally sure what the differences are supposed to be between these 2 different modes of gameplay, but it looks cool and I want to try to implement this into a 2D shoot-em-up action game of my own. Can anyone elaborate on "arcade mode" and "PC mode" for me?

Basically, the arcade mode is generally a simpler, more straight-forward game, where the PC mode has some extra stuff that you wouldn''t see in an arcade game.

A good example is Sega''s House of the Dead 2 (I think). The arcade mode is just a straight shooter, but the PC mode lets you choose which character to play as, with each character having different stats for health, weapon power, gun capacity, etc.
