In comparison to the first Doom this one was still fun and engaging, but it did struggle to bring the franchise farther in gameplay in any meaningful way. The Icon of Sin is definitely a different final boss idea than the first, but it ends up being more of a drag then an entertaining fight and I was just glad to finish up the xbox achievements once everything was over. As a game it's basically just in my opinion more episodes of the first Doom, so if you liked that one you will enjoy this one too.
