Dragon Age: Origins Tips and Tricks 1

1. I discovered that by holding down Left Trigger/L2 (brings up the radial menu) you can scan the area for items of interest and in some instances enemies. The names of said items will pop up in the general area they are in. Granted, it's a very short range scan but it is helpful in discovering secret areas and pickups you might have missed.
2. This may depend on your style of play but I wholeheartedly recommend bumping up your persuasion skill ASAP. Communication actually matters in Dragon Age: Origins (unlike most RPGS where communication is a wasted skill *cough* Oblivion) and unless you want to strong arm everyone a little tact is a good thing to have.
