I personally like Good Old Games (gog.com), a store for DRM-free and compatibility tested old games. I bought quite some games which are running perfectly well on my notebook with integrated graphics. And since the prices are low enough and I want to encourage this behaviour (DRM-free, tested), I happily pay the publisher of these old games.
