The lights are on
DA2 was OK in my opinion. It wasn't as good as DAO, but it was enjoyable. It is going to come down to your preference as a player. I would try it out first, if you're able to without buying it, and see what you think. The combat is different and the writing isn't as strong. If you can enjoy it as it's own game then you'll be alright, if you're constantly comparing it to DAO as you play through it you'll be disappointed. But even though I enjoyed it I only played it once and was done with it so, take that for what you will.
