That makes no sense. The essence of good 2D sidescrolling gameplay is the type of challenge that appeals to hardcore gamers. Why do you think that hardcore gamers are complaining about these "movies with games tacked onto them"? We miss that intensity. I''ve got an idea for an amazing 2D sidescrolling shooter. Thinking on technical terms, 3D would make the game more difficult to make, even though it would help with some things, like animation the rotating boosters on the ship. Mainly, it''s the visual effects that seem more suited towards 2D. I want it to be a heavy Anime style, down to the look of the explosions of the enemies. With animations, like a wing turning into a fist, then throwing a shockwave at a range of enemies, you''d need a good 3D artist. But during certain scenes, I want the angle of the level to change, which would make it a sound idea to do it in 3D. Perhaps a hybrid is in order...
