Portal is one of the greatest "proof of concepts" ever to hit shelves, notable for its mind-bending puzzle mechanics and humorous narrator. The game takes a while to present any true challenge, yet each puzzle seems like it could be conquered any number of ways, and leaves the player satisfied with their own solution. Unfortunately, on the PS3, Portal seems to have gotten little love--there are no patched-in trophies, and the game constantly resets to long load times that don't seem to match the hardware demands of the game!
Truly a game that transformed an era. Constantly on sale on Steam, there's no excuse for it not to be in our library. The game is the perfect length for what it is, considering there isn't much narrative to be explored in this first entry. There are some brain scratchers in here, but you'll get used to "thinking with portals".
