No, you are committing a fallacy. Just because "everyone" here pays for SWTOR, does not mean that everyone pays only for it. We also pay for other games. The market would only be filled with pay-per-month games if noone wanted anything else. But we do, as well as such games. In addition, there are many who do not play SWTOR but other games. Us playing SWTOR has no impact on their preferences. Your assertion is demonstrably false, and arguably silly (considering you are arguing your point on a set of forums linked to a publisher that has NO monthly payments for their games yet).
Besides, you also have a fatal logical flaw in your argument. You claim that if we pay for games like SWTOR, then the market will be filled with only such games. But, if we only pay for such games, wouldn't that be exactly what we want? You are appealing to our very preference NOT to have the market filled with SWTOR-like games. Either we already have such a preference, in which case your argument is moot. Or, we do not have such a preference, in which case your argument is counter-productive.
