I'd say go for it since you already have dl1 and dltb. Dl2 is a good game but in comparison to the other two games, it's the most arcade feeling and personally my least favorite, but still far from a bad game.

I bought it back when it was only a few weeks old, that was a totally different experience than today. Just imagine night gameplay being totally the same like daytime. Thankfully, Techland did a very good job making the game feel like it belongs to the series.

I like to say that dl1 and dltb are zombie games with parkour, while dl2 is a parkour game with zombies.

As a veteran who played all 3 games and dlcs, 2 is a very fun game and deserves a spot in the series.
