This just need to end. If your a Steam purist then go away. These are deals for gamers and if you don't like something whine about it elsewhere or better yet keep it to yourself. Steam isn't the best thing since slice bread anymore. It is a good program but it shows that they are not the top dog anymore. Deals are deals and if you want to pay a higher price on Steam then by all means do so but don't bring down a good deal since it isn't compatible with your all mighty Steam.
Some people like to have their games library in one place.
