A mod that i believe would add alot of really cool new aspects to the game of minecraft would be a city mod. this mod would include cars, taxis, stop lights, glowing lights, street lamps, glass doors, subway systems( subway cars and red stone powered subway tracks that would be 2 blocks wide), glass made for city skyscrapers, this mod pack would also include display chests so it would look like a side vendor. the mod would include blocks like metal grate, road lines, pavement, sidewalk, trafic light poles, and much more. this mod would make minecraft feel a bit more like real life
