The Steam sales charts are done be revenue rather than sales. Any time a game makes it into the top 10 you can guarantee it's making a crap load of money. NuTech, you keep bringing up this '120' updates figure over and over. That means nothing, it could mean 120 bug fixes, 120 new maps, 120 tweaks to the existing codebase. Quite frankly your lack of any detail and inability to think outside of an extremely small number of business practices (just 1 - loss leading) isn't helping. If you've actually got any argument outside of heresay then I'd be glad to hear it. But saying the same thing in every post isn't helping. However I do have a few games that have support for years and years, including big map updates: Battlefield 1942 Battlefield 2 Battlefield 2142 Unreal Tournament Quake 3 Painkiller Left 4 Dead CounterStrike Numerous Indie titals Many iphone apps Tribes Unreal 2 (game was a flop - but still had the money to make a very large free MP expansion) Of course the many free-to-play MMOs have numerous free updates too. I'm almost postive TF2 and Portal aren't loss-leaders. Portal was in the charts for an extremely long time, coming back in all of the sales. These charts are ranked by revenue remember, the number of sales is irrelevent as is the price per item. TF2 is in a similar position. Now, due to Valve owning steam, this latest Portal promotion will ensure the platform gets a quick uptake for the Mac - this IS for the platform. However the loss isn't there since the profit has been made, and the cost for streaming the game will be (relatively) low - certainly not enough to really dent the bottom line. Your argument is that continuing updates is impossible because a game ceases to sell - therefore putting the developer/publisher in a tricky position of making no money, but spending to do the updates. The argument other people are making is that these games are still selling - at least enought to cover the costs. Without any figures you simply cannot say one way or the other. I'm inclinded to side with the dev not being too expensive, regardless of the quantity of updates - each update seems to be a relatively minor thing, which is very cheap. You can pull off a dev or two to quickly do a few bug fixes or add some functionality. Given the ongoing sales of TF2 it's most likely covered. This is backed up by numerous other developers / publishers releasing sizeable updates for games years after release. I don't think TF2 will have any sizeable impact on Steam sales - it's only one game among hundreds. If you're saying it's a heavyweight, then you would have to admit that with that it would have made an absolute fortune and a few updates after release will not even be noticed, financially. With or without TF2, Steam will still be adding and selling games at a largely similar rate - unless it's the heavyweight of course. Still I seriously doubt you'll change your view - and that's OK too. Either of us could easily be wrong. However, unless you can prove it one way or the other - there's no point getting all bent out of shape. I mean, it would suck for the world to be flat or spherical when you thought it was the other and argued tooth and nail.
