Isometric(or 3/4 view) is what games like Jagged Alliance 2, Baldur's Gate, Commandos, Arcanum, Diablo, etc. use. It's a way of adding a bit of depth to 2D. As such, sprites are typically done in eight facings(or five and mirroring three but that results in other problems). Just angling the sprite would make it look like the player is falling over. <img src="{SMILIES_PATH}/icon_smile.gif" alt=":)" title="Smile" />
Create each angle you need, then use the suggested command.
Obviously you don't want to rotate the sprite, just set it to the angles you make before hand.
