> Even 2D games will benefit a lot from 3D support.
I don't think this works as a general statement. It depends on the game. Some can't benefit at all; Project: Starfighter is one example. And some can theoretically benefit, but in practice are bottlenecked by something else more than the graphics.
Honestly, for 2-D games, I think these cases are much more common than "a lot" of benefit. Some 2-D games really do benefit a lot from proper hardware acceleration (though strictly speaking this usually isn't 3-D), and I think Naev and Hedgewars are examples, but usually it's a minor point.
