Can you rent video games on blockbustercom

Not yet. They are still an in-store rental place. They have added the ability in which if you don't see a movie that you want, they will send it to you when they receive that title.

They are trying to integrate and use mailing systems, but they don't want to become a copy of Netflix(c) and be liable for someone suing them. Also, they aren't putting in mail right now, because they are scared of it being lost or stolen and they don't want to risk losing their ridiculously high profit (compared to other movie and game rental places).
$8 a movie > $9 a month...
