Honestly? It's fun with friends and has a few things going for it, but it is a flawed game. Borderlands 1 was a far superiour game despite lacking a story, generally having better environments, better enemies and better guns. Major flaws down below.
>Explosive weapons seem to be better than pretty much everything else making other weapons almost completely redundant.
>Your shields seem almost useless, going down in 2-3 shots, even if there are supposedly really good.
>Every enemy is a bullet sponge and are not really fun to fight. Flyers anyone?
>For a game that prides itself in have billions of guns there are not that many unique or interesting guns with only certain types of guns ever being viable.
>Because enemies are such horrid bullet sponges and do frankly way too much damage; when you do get an interesting weapon you can never play with it due to using such weapons being close to suicide.
>Environments feel almost barren and empty.
>Exploration is quite often a waste of time and when you do find a supposedly "good" loot chest there is almost always never anything of worth in it.
>Poor variety of vehicles and terrible vehicle handling.
>DLC whoring; DLC for Borderlands 1 felt like there was more effort put into it to put in generally good content. Borderlands 2 DLC felt meh and a cashgrab at best, although Tiny Tina's Assault on Dragon Keep was generally fun and interesting.
>Game feels more like a chore than fun at times.
Honestly how I feel. Not a bad game by any means but I do find myself getting bored with it rather fast.
