Dragon Age is focused both on bringing the story back into the RPG and delivering strategic elements that have been lost since the days of Baldur's Gate. Bioware did a great job of delivering on these promises. At times, the game can be tough, but hopefully these Dragon Age tips should help see you through the rough spots.

Once you've completed the initial quests and made it to Lothering, you'll be presented with a choice on what to do next. Your first order of business will be to gather the Lothering companions (Sten and Leliana) and complete the small tasks from the bulletin board just to gather some needed experience, but what then?
Your two priorities are: (1) unlock your specialization and (2) get the best companions.
For a warrior or a rogue, Wynne makes a fantastic companion. She's a spirit healer, so she'll keep you up and in the fight. Wynne can be found at the Circle Tower, but be aware, part of this quest requires going solo for a bit. You'll be given some tools to help you defeat the hardest monsters in this area, but at first, you'll be by your lonesome. Get some healing kits and make sure you have enough combat arts to dish out some damage.
For a mage, you'll probably want to let your choice in specialization guide you. For example, if you want to go with an Arcane Warrior -- which is one of the most powerful specializations available and great for non-healer mages -- you'll be headed toward the Brecilian Ruins.
As for what specialization to choose, that is going to be a matter of playstyle. I do think that shapeshifter is cool but not-so-useful in that you'll mostly want to be casting spells at the enemy. If you do want to mix it up in melee, Arcane Warrior is far more powerful in the long run.
Also, the ranger specialization for rogues will give your backstabber an extra tank. It might not sound as cool as assassin, but it adds more survivability to the hole group.
Warriors have a lot of great specializations to choose from with Champion being Bard-like in its ability to boost the strength of the whole party and Berserker being great for focusing on increasing the damage of the warrior.
