Deus Ex: Invisible War vs Portal 2
Deus Ex: Invisible War
Deus Ex: Invisible War is the first sequel to the Deus Ex game franchise and is perhaps one of the least known version. Set in a world 20 years after the events in the first game has concluded, Deus Ex: Invisible War lets you take part in the dark struggle between massive religious sects and powerful political factions that are hellbent on setting up and securing a world government that will pass policies that are in their favor; policies that will change the human society for decades and maybe centuries to come. The storyline in this game may be dark and dreary, but it is supported by plenty of responsive plot branches that will shape your narrative based on your actions and decisions.Aside from the many amazing new augments added to your arsenal, Deus Ex: Invisible War even has a much improved AI and stealth system where enemies will actively seek you (the intruder) out even when any sound is detected. This makes its stealth gameplay a whole lot more challenging. Of course, like the previous game, you'll also be given multiple (more peaceful) ways to avoid conflict if you so wish to.
Deus Ex: Invisible War is unfortunately the black sheep of the franchise. It has plenty of problems and let's not even mention about the incredibly long loading screens. Honestly, if you can afford the other games in the series, you might want to get those instead.
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.
