My thoughts. First of all, you must understand I am not into games like Diablo which Borderlands bases some of its game mechanics on (don't know what I should call this genre). I prefer my FPS games to be more like Half Life, Return to Castle Wolfenstein, and Jedi Knight.
I will write down first what I did like about Borderlands 1. I liked the free reign which was big enough (sometimes a little to big) to just go around and explore between assignment and the various opportunities to improve XP and get more stuff to sell.
I also like the graphic style in general, the scenery such as the towns, abandoned factories, military bases, a lot of the characters designs including the Atlas/Hyperion soldiers, the creatures, the aliens and so on. The raiders on the other hand were sometimes so ridiculously overdone but I understand that is part of what they should represent; psychopathic anarchists.
My favorite part of the game is when the player finally confronted Atlas and then went to the vault.
In general I also liked the more "story" driven DLCs (if you can really call it story driven, it is not really like the FNV DLCs) such as the zombie themed one (the Scooby Doo parody was rather amusing). General Knox and the Claptrap one offer more of Borderlands general content but sometimes felt that they dragged on to much.
The gameplay in general works but as I played alone I did not have any team experience and Borderlands is really meant be played with more people.
I also did not try out all of the characters during my sessions.
But the humor... the humor is sometimes very hit and miss for me. Either being sometimes very ridiculous or playing on tropes and memes which can make it very dated for people who may play it years after the release.
I get it, this is part of the Borderlands atmosphere but it was rather lost on me.
There is also very little interactivity with the NPCs in the game, Markus, Dr Zed, and Scooter do their lines and try to do quips, but I never really felt any kind of attachment to these characters and to be honest I found claptrap to be really annoying sometimes.
The only character I found somewhat amusing was the stereotypical evil Hyperion department leader and I wish he had featured more prominent in Borderlands 2 as I find Handsome Jack a rather obnoxious asshole.
As for the regular NPCs, they are just background, occasionally asking me if I have seen their gun when I pass them by.
Borderlands 2. Well it is more of Borderlands 1.
It refines and improves on elements from Borderlands 1 and I am glad to see there is a bit more storyline now, but it raises the ridiculous and sometimes irritating humor to eleven.
Sure, some parts are amusing and will get a smile or a grin from me but never really a loud out laugh.
As I mentioned before I find Handsome Jack an overhyped antagonist who constantly keeps spouting lines on how powerful and evil he is and how full he is of himself.
I know, that is his character and players are suppose to like him for it or hate him, but I just wanted him to go away and bother someone else.
Many of the characters seem to have been made as obnoxious or irritating as possible in an effort to make them seem humorous such as the little girl.
And the scientist seems to have lost even more screws.
I didn't really get far in this game, at some point I really did not feel like continuing as I found the main quest of getting even with Handsome Jack not really that interesting.
I also did not like that I had to spend real money on getting keys or gems to unlock special weapon cases.
And why did the designers cut out the medical kits/health boosters from the first game. To encourage even more to work together.
It has been a while since I played this so i don't recall everything clearly.
I never felt like playing Borderlands Pre-Sequel or Tales from the Borderlands.
