nowhere near a perfect game but good god is it a lot of fun. it has a lot of pros and cons; the main con being the horrible writing, but the gameplay heavily outweighs that in my opinion. it's genuinely so much easier and exciting to play than the previous games it's not even funny. the weapon handling has improved (except maliwan guns but nobody cares about them anyway), climbing & sliding mechanics were added, the fast travel system is almost perfect and probably lots of other stuff i'm currently forgetting.
hopefully the next main game will combine the writing of bl3 and the gameplay of bl3 and we'll finally have a perfect game.
