The best thing about 3D is that it expands the gameplay possibilities, but often those possibilities are not taken advantage of so it really doesn''t matter. Warcraft III uses 3D graphics but has 2D gameplay, so the 3D engine isn''t really that important for that game.
As for realism, I wouldn''t say games are becoming too real. I would say too many games are becoming realistic. I''m all for 3D as long as the system requirements are reasonable, but I hate the flood of stupid WW2 games.
