Of course. I typically am bored to death by First Person Shooters, and think the first Bioshock is nearly unplayable, but I had more fun with Bioshock Infinite's single player than any campaign since...Uncharted 3? I don't know, my memory is bad. I'm tempted to say it was my favorite campaign of the generation taking both gameplay and story into account.
I recently re-downloaded my copy to play Clash of the Titans JUST because of how much I liked the gameplay, but for whatever reason I haven't actually bothered to get the DLC yet. I am genuinely psyched to dive into that eventually, though.
