I woke up and asked myself this morning "I'm selling a game, how should I sell it?", and I found this thread. After reading it, I didn't feel like I had anything like a good answer.
Nonetheless thought I'd update the OP as well as I could, updating fields.
Updating this as best I can (leaving in facts I can't verify/not verify). Lots of missing info, so if people have anything to share... .
One thing of particular interest is customer support, which isn't mentioned too much below.
I'm also aware that I'm picking on paypal for the VAT thing when it's true for other sellers as well I think (google checkout in particular, I think?).
Google checkout doesn't seem to be america-only anymore, though I haven't seen anyone using it for selling games...
Some places I couldn't get any info about - Direct2Drive, GamersGate. If anyone knows about those, would be good to know.
