Borderlands

I was pretty unimpressed by this game. It was made quite a few years ago, and has since improved on its name greatly. 

You get dropped off at a base with a friendly Claptrap Robot.  You have a mysterious female giving you missions.  Where did she come from? What does she really want?

Like traditional RPGs, much of the players' time will be taken up by missions. There are 127 missions of varying length and complexity, 47 of these being part of the story and the other 80 as side missions. Many of these missions can be completed together. Gearbox wants to encourage players to push themselves just a bit further to complete the next mission on their list. Each mission carries its own rewards, such as new weapons and items, or perhaps revealing a new piece of the story.

After completing the game, players are free to roam the world and wrap up any side missions left unfinished, drop the Vault key off at Tannis and collect their reward and wander around aimlessly. After returning to the title screen and choosing characters however, players can choose to begin the second playthrough.

On the second playthrough, characters have all of the gear, skills, levels, and money that they ended the game with. All of the enemies scale up, with bandits beginning at level 34, and ascending from there. The names of enemies also adjust to reflect the difficulty setting, i.e. from psycho-maniac-lunatic, midget-little-stunted and Bruiser-Brute-Bully.

At the end of Playthrough 2, all of the enemies scale again, ranging from 48-52 and dropping even better loot than before. Players can revisit and battle most of the bosses, and fight for better gear, participate in cooperative play, and fight in the arenas. Colloquially referred to as Playthrough 2.5, marking the completion of Playthrough 2's storyline missions, all enemies and missions scale to either two levels below or above the character and adapts as characters level up (this carries over to the DLCs, and will significantly increase their difficulty when Playthrough 2 of Borderlands is complete).

Save spots also let you play around with your selected characters colors. 

Upgrade your character and weapons as you complete missions.

There are also many achievements you can get.

My overall opinion of this game is very low.  This game does get better and better with the new sequels.  This game in its prime was amazing.   Wikipedia did give me the information on the backstory as the game doesnt offer much itself.

Looking forward to trying the sequels.
