this game is soooooooooooooooooo well put together,it has all the makings of a great game,shooting,weird weapons,it creeps you out sometimes,and a sick boss battle at the end.plus a bunch of other stuff that separates portal from other games out there,for example.its funny,it uses mechanics that are hard to find in alot of games like physics,trajectory and a bunch of other things that will get your brain moving.some people think its to short,and it is,IF YOUR A GENIUS!!if you were to complete all the puzzles without having to try more than once or think some of the puzzles over you would be done in about 2 hours,but if you have an average brain,it will take you alot longer,not to mention the fact that this game is so addictive you will want to play through it again and again.and all the crazy maps and mods you can get for this game you be messing with it a loooooooooooooong time.not to mention the advanced maps and challenge maps under the bonus map section.really only has on flaw that keeps this game from perfection.its a little on the hard side but not impossible.
to summarize,this game is great and if you have a brain and a computer that meets the requirements just buy it!! orange box-crap=portal

p.s.my time spent playing is only for the main story,not all the stuff you can do
