EA, which owns rival service Origin, says you will not be seeing such sales via their platform.
Says Origin boss David DeMartini: "We won't be doing that. Obviously they think it's the right thing to do after a certain amount of time. I just think it cheapens your intellectual property.
"I know both sides of it, I understand it. If you want to sell a whole bunch of units, that is certainly a way to do that, to sell a whole bunch of stuff at a low price. The game makers work incredibly hard to make this intellectual property, and we're not trying to be Target. We're trying to be Nordstrom.
"When I say that, I mean good value, we're trying to give you a fair price point, and occasionally there will be things that are on sale you could look for a discount, just don't look for 75 per cent off going-out-of-business sales."
Origin is the second largest direct-to-consumer gaming platform, with 11 million registered users. Steam has 41 million.
