@garry: games (including ads, and other deals – without taking into account the fact that my games are being quite important indirect promotional vehicle for my other businesses, and other game/non-game referral programs. Games are playing important role in this whole system, so I would need bit more clarification what you mean by asking question “games” or “referral” to be able to give a proper answer.)

Practical example: let’s suppose somebody creates a game to attract gamers to buy other games (through referral link). He is not making money directly from the game, but from the referral program and ads – the game is an important promotional vehicle between. When somebody asks: “are you making more money from games or referral programs?”, it would be pretty difficult to answer since he might have closed deals thanks to his freeware game that provide him income – his game earned him the deals and are part of it. Some developer are doing deals like that using their free (for players) games.

If you meant “direct sales” versus “other ways to earn money with games” then the answer is “others” (since at the moment I have only freeware games, and no direct sales).

Hopefully this was clear enough answer :)
