I rusty on my conversion rates.
That's about $20 USD, right?
BioShock 1 was excellent for its time, but BioShock Infinite, IMO, struggles under its own weight and embarrassingly uninformed view of Christianity (even if Christianity is used by the writers as nothing more than window dressing for the threats of blind religion and hypernationalism).
I haven't played BS2 because I could never get a straight answer on whether it has SecuROM packed in or not.
BS1 was slow to start (and restart; the beginning isn't very forgiving if you're like me and tend to not conserve ammo very well), but had what I thought was a really interesting take on unchecked humanism. The gameplay was pretty cool, too.
