Infinite Exp/Money
Choose a sidequest that does NOT end with a cutscene or dialogue tree. Usually finding an item or something of that nature. Draw your weapon near the NPC, but without finishing the quest. When you approach the NPC wait until your character begins to re-sheath their weapon. As they are putting it away press X repeatedly(PS3 version)or A (for the xbox 360 version of the game) and each time you press the allotted button you will be awarded with the quests reward in money/exp over and over.

Joss Whedon Reference
During random companion dialogue in the city between Anders and Isabella, she mentions that abominations are easy to escape because they make loud noises like "Grr Argh", which Anders refutes saying "Abominations to not go Grr Argh". During the ending credits of Buffy The Vampire Slayer, Joss Whedon's "Mutant Enemy Productions" credit screen shows a little monster which says "Grr Argh?"

Sir Mixalot Reference
Take Isabella into the fade in the desire section. The demon will seduce her with the prospect of a boat in the harbor. When Isabella turns on you, she will say "I like big boats and I cannot lie", which is a reference to Sir Mixalot's "I Like Big Butts" song.

Wizard of Oz Reference
In your home when your mother says that her children should be nobles now, your uncle says "And if wishes were poppy we'd all be dreaming right now".

Recommended Party Configuration
It is best to plan your party from the start. While planning character roles, remember "One to take it, one to deal, one to weaken, one to heal". You should have a damager, tank, entropist and healer. This will ensure you have one member taking all the damage and bringing the attention away from the rest of the party. Have an entropist (probably Merrill) to weaken and demoralize the enemy, a healer to strengthen and maintain the party, and a damager to inflict the pain. This will ensure a well rounded party that covers all aspects of combat.

Unlock Blood Dragon Armor
If you have a save of Dragon Age Origins on your hard drive with the Blood Dragon Armor unlocked, it automatically transfers to Dragon Age 2 as well.
