You can romance Zevran with a male Dwarf and get this scene - http://www.homodwarf.pt.vu/
USE TACTICS. Automate potion usage, healing spells, modes and commonly used spells/talents. It will help a LOT.
Mages are overpowered. Force Cage and Crushing prison are the main offenders, but so is the Glyph line, Paralyze Line, Hex line and Cone of Cold. Also, every mage should have the Heal spell, perhaps even Regenerate. Dropping a spec point into Spirit Healer for Group Heal is also a good idea.
You don't need Lockpicking. All locked chests in the game contain crappy loot. If you want to make money, level Stealing. It's pretty great. To disarm traps, you need a Rogue with Trapmaking, but most traps can be avoided or healed through.
Daggers are currently bugged and are not getting the damage bonus from dexterity that they should be getting. Bows are just crap, except for one talent (Arrow of Slaying). They are getting fixed in a future patch. DPS-oriented rogues should get some points in Strenght and use Swords. Or at the very least get Lethality and a high Cunning score.
Dog is crap. Until he gets Overwhelm. Then he's great.
Morrigan disapproves. A lot. Get used to it. She is, however, easily distracted by shiny jewelry that you can get cheap from most merchants in the game.
