Borderlands was a solid 8.5 for me and one of my favorite games of the generation. I LOVE the loot whoring style of gameplay. Nothing like running across a legendary gun that's exactly what you need. Love the humor in the series, too, and how it doesn't take itself super seriously. It also had some excellent DLC. Unlike most FPS games, you can keep going back and having fun.
A lot of your Cons are issues that other people mentioned when the game came out and which Gearbox addressed in Borderlands 2.
Cons
-Storyline is a bit generic mainly the main campaign MUCH better story in BL2.
-Environment does not change often and is usually bland at times Gearbox made a big point of adding in different environments in BL2.
-Amount of characters in a large world makes the world all too barren and somewhat boring BL2 has a lot more characters, both returning and new.
