Neither have I, and I never said that I have. But I have seen old games, still supported and still selling at original price. No BS here. :)
A-10C may be old, but is by no means subpar nor unsupported. I submitted an A-10C bug report yesterday and expect it to be resolved at some point. I wouldn't bother doing so with other games of same age.
Considering relatively frequent sales, bundles and bonus system, there's no reason to complain about the prices.
