that's a pretty good deal! thanks CheapyD
another option will be the Augmented Edition from GMG -which is 40USD- after a 20% discount code
or if you use a referral -points below-, it'll be effectively 35USD (u get the 5USD as future credit)
but... you don't get the Tactical Enhancement Pack and the Deus Ex GOTY given cannot be activated on Steam (it can be traded in on GMG for 2+ dollars though)
