HONK!
Maybe its the mischief, maybe its being able to fuck with the British, but this game is so fun.
Couple of tricky points, i in fact had month stretches where i never played the game, but overall very cool!!! love the adaptive soundtrack especially :)

Oh god the nostalgia. Ive completed it now on 360 and PC and its just such a good game. Excellent level design, soundtrack and V.Aing. Its such a good introduction to FPS as a whole because its just so easy to understand and lets new players get accoustemed to FPS-related things like moving a camera, reaction time, firing and aiming
idk if the above makes sense but its how i feel. I think i wouldn't be the type of gamer i am today without Portal 2

While i think the concept is really cool, i find it really difficult to get into.
I had a friend explain to me in-depth how it goes and i watched him play for like 2 hrs.
But when i tried to play it myself its so very overwhelming, especially for anyone who is a casual gamer.
If you have the ability to commit to learning, i think this game could actually be really fun. But it just wasnt for me.
