With the first 2 Borderlands games, I was impressed mostly with the narrative/comedy. With this installment of the franchise, the biggest winning factor for me was the gameplay rather than its narrative. First off; lemme just say playing as Clap-trap was a flippin blast! With his added remarks to the campaign, I think it made this game much more humorous than say you just had Athena commenting about stuff. Another piece of the plot I enjoyed was seeing Handsome Jack again as I thought Borderlands 2 was the last I seen of him. Now regarding the gameplay; really just all around awesome. Of course the low gravity is what makes this game so great. Able to jump over areas, move around more quickly, and even getting a new vehicle called the Stingray makes travel so much fun and fast as you can jump over literal mountains if you get the speed/jump/angle right. I also loved the cryogenic weapons so much better than the slag weapons, so I'm glad they were switched out in this installment.
I loved the setting on being on Pandora's moon Elpis. Don't get me wrong; Pandora is great, but we already have 2 games plus the DLCs that are set on that planet. Being on the moon with low gravity was refreshing, and makes me excited to check out its DLC and the sequel (also Tales from the Borderlands too)
