Quick question...
If I buy the DVD version of this, am I right in thinking that I can just enter the CD key into Steam and download it, thereby not having to use my (broken) DVD drive to install OR run it?
It appears a few quid cheaper on DVD but my drive's knackered...
Cheers.
I think you can yes. But you're really best waiting for the christmas steam sales - if you can. You should be able to pick up L4D/L4D2 for a couple of quid.
