I'm not using the word 'game' here, because I think the more accurate word is 'simulation'. I've been working on it little by little for the last several months, and wanted to put a feeler out there.
What I'm creating is a football simulation WITH graphics - something that does not really exist right now. But this thing is not a game. It would be realistic in every conceivable way. If a fat defensive tackle picks up a fumble and runs 80 yards, he will get tired, gasping for breath, and slowing down drastically, maybe even falling down towards the end. Players can trip and fall, Two receivers can have the same speed, but one might be able to accelerate faster, and one just may run the wrong route on a play, because he hasn't fully learned the playbook. You may have a star who doesn't like to stay in shape, so he slowly deteriorates physically.
I've already completed the player generation and scouting. Players are rated 0-119 in each attribute, divided into 3 categories: Football skills, Physical Skills, and mental/behavior attributes - but you only see a broader summary value of each - (0-11). Ratings are seen through scouts, who also have a scouting error.
I'm working on this thing piece by piece, 1 football fundamental at a time. If the players can't accelerate and decelerate properly when they run, nothing else matters. I've got that down. I'm working on kicking right now. Next would be throwing. Then after that blocking, etc.
Below is a screenshot showing what the players look like in a kickoff formation (I am still tweaking these, I have since made the shoulder pads a little less wider).
These youtube videos don't do this justice, but it'll have to do until I figure out how to share higher quality videos.
I've been working on the kickoff animations, and how a player's attributes affect the kickoff itself. It's hard to see, but notice how the ball can bounce funny after it hits the ground, just like in real life. Some tweaking may be necessary. I also made the length of the shoulder pads a little shorter - but you probably won't be able to tell that in these videos. Also note that in all videos, the kicker is aiming to kick the ball right down the middle.
Below are 3 videos demonstrating 3 different kicks by the same player with a leg strength rating of 6, and a kickoff accuracy rating of 6.

Below are 3 kicks by a different player, but this player has a leg strength rating of 9, and a kickoff accuracy rating of 0.
