Even if you compare the sales of RPGs as a genre back in 1997, you will see that RPGs, compared to other genres of games have never sold well. Fallout 1/2 did not sell well compared to other types of games, and that trend remains today. Although the overall game market is much larger now, the PC platform continues to shrink and the combined console marktet continues to expand, in relation to each other.
So we have two trends here: RPGs perform poorly vis a vis other game types, and console games routinely outsell even the best selling PC only games. The article linked previously in this thread showed that 19% (If I remember correctly) of FO3 sales were for PC.
So, I agree that comparing FO1/2 sales with FO3 sales is generally worthless, the point was to counter the argument that FO3 has not been financially successful, which is untrue.
This argument also shows why, for financial reasons, FO3 is not a pure RPG.
Of course, WoW completely invalidates all of the points you make. Almost as many copies of that single RPG game sold as there are 360's. The PC market is quite healthy, what isn't healthy is the piracy rate. IIRC there was one game recently that sold only 600 copies, but was pirated several thousand times. The PC market isn't shrinking at all, give the console market a piracy rate the same as the PC market, you'll watch that die too. Give the PC market a solution to piracy, you'll see it go back to well beyond the console market.
Piracy is the issue, nothing more. As previously stated, WoW pretty clearly demonstrates that. Not every PC Gamer is playing WoW, but there's almost as many subscribers to that one single game than there are 360's.
As far as financially successfull goes, once again, depends on how you want to consider it. Did it sell 2.7 million units? Yes. Is that good? No. Why not? Because they expected sales well in excess of 4.7 million. They budgeted for sales well in excess of 4.7 million. How can you tell? Because their initial shipment was 4.7 million units, which means they expected to sell at least that many, because you always ship less units than you expect to sell by the time the product goes off the shelves. For the simple reason that any units that go unsold get credited back to the manufacturer who now has to pay disposal costs on unsold units.
So they sold less than they expected, and they're bankrolling 3 studios on Bethseda's income, with no further revenue in sight for at least 18 months or more. Since there's no announcement of any further imminent products. They'll burn through whatever revenue they did get, minus the returns from stores, at a pretty decent pace, and they'll have to adjust schedules to generate further revenue, likely forcing Bethseda to rush TES V.
So yes, it is failing. It is falling well short of expectations, and the ramifications will be felt for years. They expected to sell > 4.7 million units and they actually sold ~2.7 million before dropping off the charts.
This is just math. Figure they have 3 teams they have to bankroll, executives, hardware, software, electricity, water, sewage, rent for 3 buildings at least, maybe 4, office supplies, testing teams, off-site data storage, 'net access, cleaning crews, etc. It's a pretty hefty burn rate, and all of it is being carried by one single studio which releases only one single title year by year.
So I'm not real sure where anyone gets a win here when they didn't sell what they thought they would and now have to find a way to bankroll a whole lot of stuff for the next 18 months.
