Keep on it, it will only get better and better. This was the 1st RPG game I ever played and I thoroughly loved it, mostly because of the story and the attention to details. I finished it within a month (mostly weekends) which is kind of a record for me considering I take months finishing linear FPS campaigns. I am on my 2nd playthrough, this time trying to complete all side quests.
My personal update to this thread, started Borderlands 2 with a couple of friends in co-op, Man I haven't had this much fun probably since the Bulletstorm
Borderlands is amazing fun and a time sink - I've sunk 60+ hours in a lvl 49 Gunzerker
