there are four problem with FPA (first person adventure?
) -
1) they tend to be a 'myst' style games. and i personally don't like 'valve riddles'.
2) they tend to put less weight on the player character, i personally like to see who am i playing.
3) usually these games has problem with navigation (don't tell me you never got lost int these games).
4)sometimes the FP POV is used to cut the costs of creating human characters. and so the game world becomes dull and empty. (best example - mostly every myst style games, not such a good example - starship titanic)
