Coming back into Dragon Age 2, and yeah, I like it.
The first thing that I notice is just how snappy the combat feels. In DA:O, as a mage, I just vaguely wave my staff in the direction of an enemy, or use one of 3 animations for all of my spells. In 2, im spinning my staff around like a ninja, and fireballs explode the enemy's torsos. It really activates the 4 year old side of my brain. I know it sounds dumb, but I really cannot understate how dull it was visually, to play as a mage in DA:O.
That said, whilst I never really had an issue with it in previous playthroughs, it is quite frustrating to set up your party so that you have your melee characters in front, with your ranged companions in the back, only for a group of enemies to just appear out of thin air behind you - especially as they are coming from a path that you literally just cleared out.
Cooldown timers are also much longer, too. In DA:O, my Heal spell had a cooldown of 5s. In DA2, it is 40s. Fireball goes from 10s, to 20s. Winter's Grasp from 8s, to 20s. I definitely have to be much stingier with when I choose to use my abilities.
Otherwise, I really don't mind the changes to the dialogue. I like having a voiced protagonist - though it is always odd when the text says one thing, and your character says another - and having spent a significant amount of time with ME this year, the dialogue wheel feels right at home. Im not going to deny that it is a downgrade vs DA:O, but I really don't mind it.
Overall, there have been quite a few mechanical changes, which makes the game feel quite different. I am still enjoying it, though.
