So I got to thinking how one makes switching between different user profiles easy and practical.
Easy enough making folks create the profile in the system's OS on boot. They could even have a few guest profiles that would have preferences set to a few common expected setups (maybe you could even tweak the guest profiles, or create more "guest" profiles).
In any case, how does one best incorporate this into a game, especially hot seat games.
For example take Super Smash Brothers Melee, whose solution involved using the cursor to select your profile. Now a similar concept could be used for Brawl. However, could they use a quicker way to recognize players? Some time of recognition software utilizing the camera (if there is one), thumbprint reader (cheep enough tech?), or some other means. Obviously games should have a way to select it manually, but such recognition software would speed up the process quite a bit.
