One feature I would love to see in future versions of SMBC are some ganeplay modes that add some random elements to the game in order to greatly enhance replayability. Some ideas for random features include: Random Question Block Items Randomly makes all question blocks in a level either give you one coin, multiple coins, a power-up, a one-up, or a star. The chance of a question block being a particular item would approximate the distribution of most levels, e.g. a 65% chance of a block being one coin, a 15% chance of being multiple coins, a 10% chance of being a power-up, a 5% chance of being a star, and a 5% chance of being a one-up (of course question blocks containing vines would not be affected). This encourages level exploration and makes each question block a true unknown with each play through. Random Enemies Each of the enemies in a particular level are randomly selected so that the player cannot predict which enemy they will encounter at a given time. Lakitu and/or Bullet Bills and/or Flying Cheep Cheeps would randomly be chosen to appear in a level (perhaps dependent on difficulty level). Piranha plants would be placed at random on pipes throughout the level. Random Secret Areas Location Makes the secret areas that are accessible from a pipe/vine appear on a randomly selected pipe/question block containing a vine. This again encourages exploration in each level. Random Environments All day, night, underground, castle or snow (e.g. World 6-3) levels are randomly chosen to be either in the day, night, underground, castle or snow. The background, enemy colors, and music would match the environment chosen. I had previously suggested all of these modes in the Wiki, but I'm posting them here for discussion.
