well, EA did fairly well in the Need For Speed Series, a tad unrealistic in the car being indestructible but the physics system seemed solid, you drive 240 mph and you make a sharp turn, your car will flip! = woot!!!
EA did a fairly great job with spore, I tried it and enjoyed it.
EA could actually do a good job with M&B, EA would probably help M&B work up the graphics, but only problem I see, is they'd make the player more powerful in game.
