resistance on psp is a 3ps? i think so.. as i said, its easy to do but a but unecessary, i wont run from a game because i cant see my digital reflection in a mirror but as i said, easy, what i would do:

create a fully animated player first, then attach the cam to his head or chest, then walla, first person view with the ability to look in mirrors, there are more advanced ways such as creating a player model that is only visible on other cameras and such but once again, you'll hardly need this in a single player title, the titles listed above mostly have multiplayer so its expected thet there is a character model, for indie developers, dont waste time on eye candy effects unless CRUCIAL to your game type... this effect could be added ages from now
