I don't really see a problem with triangulation.
After all, it has to be triangulated to be in-game right?
It isn't supposed to look triangulated, it's supposed to look flat. Triangulation looks ugly and makes any model look worse. Unless there is a reason for the triangulation, it should be avoided.

there, not to much triangulation right?
That's the wireframe. If you looked at it when it was correctly shaded, you wouldn't see the triangles.
You do not want to see the triangles. It is made of triangles, but two triangles makes a rectangle, therefor it should look like a rectangle.
