Don't forget it's a game first and foremost, as such is recommended to take liberties regarding game play mechanics for ease of use if nothing else just for the comfort of the player. While of course a person can't control their direction while jumping in reality(nor can they suddenly jump 10 feet straight up into the air) but it's because it's a game that you can add in logic-defying physics. Though you find it 'idiotic' that most video-games aren't realistic, all I can suggest is that you go outside and play a sport or something.

A point I want to bring up is, should the game's jumping really need mastering? Why can't things be simple and fun? It's often games with very simple combat mechanics that end up being the most competitive. When a person doesn't have to wrack their brains just for the most basic of movements, it means they can just focus on tactics or their spatial awareness.(though now that I think about it, adding air control is technically adding complexity to the game, not making it more simple)

Although the reference isn't entirely relevant, I mostly just want to note that 'realism' hinders game-play in several places besides jumping:
Dark Souls is argued as a hardcore game, and it's melee combat only has three basic principles that is easy to pick up, yet the difficulty and PvP content remains in-tact regardless. The principles being; attack, defend, and dodge. Dodging itself is extremely simple yet hard to master of course. Getting to the point, you can't just up and jump several feet in whatever direction you choose, so as far as realism is concerned, dodging isn't an option which would leave you with two choices, attack or defend. This gets annoying fast, as there isn't any form of convenient movement that would allow a player to extend or close the distance and perhaps catch the player off-guard, or escape any sort of sweeping attack unharmed. The tactics have now been severely limited due to a lack of a single feature for the sake of realism in the game.

Jetpack for boosted jump, i hate building a wall around a fort, then falling off the wall out of the fort and cant jump over it -_-

They really need more control on how the player moves. Especially running forwards.

I would like to put out a HUGE apology. Some things came up in real life and this project was the absolute last thing on my mind. I have to work at a fireworks stand with my NJROTC unit doing inventory, then I have a week of bootcamp beginning on Monday the 18th. I have a week more of fireworks stand tending and then I get flown off to Florida to visit family members. In hindsight, I probably should not have started this project knowing that I would be absent much of the summer. I'm going to do my best to get this updated this morning and during the time I'm not working the fireworks stand, but I absolutely will not be able to update from the 18th to the 23rd. I'll see what I can do about securing a decent computer for the time i'm in Florida.

If you give us permission, we the mods(Or just me) will be happy to edit your list while you are away.

Be my guest!

If they'd like, everyone can also make his job easier by putting their suggestions on this topic instead of creating a new one. It'd help a great deal

Yes it would; and Aly, when would you like me to begin?

Are there certain idea you're looking to add in, or simply any suggestion that is well described and worded.

Not to offend you, but you are in the vast minority here. Its widely accepted in the casual and competitive community for Halo, Tribes, Quake, and more that being able to control your jumps is better, as it is. It makes escaping much more possible by adding more angles to possibly make the jump. It also makes strafing more skillful, making it harder to hit shots on people who know how to dodge.

What if they added a server-side option to turn various physics and properties on and off?
