Borderlands: The Pre-Sequel vs Portal 2
Borderlands: The Pre-Sequel
Borderlands: The Pre-Sequel is supposed to be the Borderlands game that occurs in between Borderlands 1 and 2 as it details Handsome Jack's rise to power and wealth. The game features a pretty similar frantic gameplay to Borderlands 2 with a few major changes - Borderlands: The Pre-Sequel is set in space and on a planet with low gravity and limited oxygen supply. These factors do bump up the difficult of the game by a notch and it is incredibly fun to enjoy the virtually-designed low gravity effect in first person.Like Borderlands 2, this game brings along with it a brand new cast of anti-heroes, each with their own set of special abilities. Interestingly, you get to play the annoyingly amusing (or is it "amusingly annoying"?) little robot - Claptrap - in this pre-sequel too! Of course, being space, you'll get a new line of vehicles to wreak havoc in.
If you're here for the story, then you'll won't find Borderlands: The Pre-Sequel disappointing, but when it comes to its gameplay, it does feel a bit lackluster at times. All in all though, the game bridges the story perfectly and is pretty much a must-buy for fans of the series, but if you're new to the series, it might be best to start with either Borderlands 1 or 2.
Portal 2
Portal 2 follows in the footsteps of the award-winning original while continuing the story of Chell and Glados. Now with both single player and a 2-player cooperative mode, Portal 2 ramped up its game with a plethora of new, challenging puzzles, a storyline that's a lot richer than before, and more advanced and realistic physics that will govern your gameplay. Interestingly, the game also includes editing tools, allowing players to create their own puzzles which can then be shared for all to enjoy.Portal 2 is definitely a much better game in the series and if you fancy giving this franchise a chance, you might want to jump straight to Portal 2.
