seriously , people , if you have a irrational hate for steam or be too dumb to use it properly - why do you keep buy the game base on it ? the information about this game use Steamworks be available long before , anybody willing could research it easily before buy this game . why do you have to show you own stupidity\/laziness by announce that you find out about this game 's Steamworks usage only AFTER buy this game ? for the record , I have be use Steam service since it be beta stage , on multiple pc -lrb- both windows-based and macos-based -rrb- , I have close to 200 title purchase through it , and I have never , ever have experience any kind of issue when use it almost every day , same go for 100 's of 1000 's of other user . have you ever give a slightest thought that if majority of people be use this service successfully that the problem that you be have be cause by the `` thing '' located between the chair and the keyboard , and not the valve software ? and before you try to critique steam further - guess what ? buy this particular game directly through steam be the only way to ensure that the game you be buy be not tamper with and you would get exactly what be advertise before the actual sale . not like with Amazon 's physical copy of `` augmented edition '' pc version of this game , where they be advertise of have a `` bonus code '' for `` Tactical Pack '' , but do not actually include any of such code -lrb- read up the product discussion board for this particular version of the game -rrb- , or like with GameStop 's physical copy of this game , which be tamper with by GameStop -lrb- Google it , the GameStop have officially admit that they intentionally remove a certain `` bonus code '' from the box of this game before reseal the box and sell they as `` new '' to all the customer -rrb- . because of such issue , this -lrb- hopefully -rrb- will be the last game I 'll ever purchase in physical form , all of my future game will be purchase through digital distribution service , be it either Steam , ea 's origin or something else . as for the game itself , so far I like it -lrb- and I really , REALLY love the original Deus ex and absolutely hate the sequel and other game that attempt the emulate the same experience\/gameplay type -rrb- . I would say it be still not as immersing as the original `` Deus ex '' , but it be a very faithful reproduction of it -lrb- the best one so far -rrb- when it come to write storyline , environment design , sound design and other various gameplay element -lrb- such as inventory system , the HUD , the weapon system , the `` alternative level progression path '' and so on -rrb- and a very `` polish '' -lrb- in term of the game 's stability\/performance\/bugs issue -rrb- overall product . exclude the issue with the `` bonus code '' I would say it be well worth its price . for people who also like this game , especially for its storyline\/settings , I would also recommend read the related fiction book , `` Deus ex : Icarus effect '' , which storyline happen in the same `` universe '' , start a little bit earlier in timeline than this game and involve different `` main character '' , though also include the one that you 'll see\/meet in this game -lrb- for example all of the mercenary character that participate in the initial attack on Sarif Industries lab -rrb- .
