User blog comment:Dr. Clayton Forrestor/Borderlands 2 on Steam or not?/@comment-667748-20120228220520/@comment-3126875-20120229010558

i hear that, i purchased portal on steam some time ago, not knowing that it required steam, so at the time i had no internet connection (i've got no net on my pc atm, using my phone) so i couldn't even install portal, let alone play it.
