I don't like Origin mostly for the fact that somehow I'm never included in any of their sales because apparently I'm in the 'UK' or some shit like that. Whereas when Steam has a sale its a sale across the board, not based on territory. I don't live in the Us or Canada and that shouldn't be a factor in if I get a good deal from your service or not.
Origin is still light-years away from Steam and I don't see it changing anytime soon. I have no interest in becoming a customer of theirs at this time.
