There is only a gap between what you want and what you get if your interests are out of the norm. As long as there is a market for the product or service you are wanting (and often, though not always, there is), the market will be there to provide it for you. In this way, the market serves to effectively provide the interests of the majority of people. Since the vast majority of people want their games in 3d rather than 2d, the market has responded to that, providing the products that most people wanted.
If enough people really wanted 2d games rather than 3d games, what makes you think tons of companies would be jumping at the opportunity of producing 2d games rather than 3d games? Because there is simply likely no market for them so long as 3d games are there and so long as people prefer the latter form of game.
