Gemma 4 Flight Sim
Make a 3d flight simulator game with lots of detail, contain the result in a single script so it can be opened in a modern browser.
QB Simulator
Design and create a quarterback simulator game. The game must feature 3d graphics in a any style you choose. A start screen on a football field background allows the user to select from one of two positions, quarterback or receiver. Once the player has selected a position and the game is started, the quarterback position will throw the ball to the receiver, using a control map that you deceide on. If playing the qb, the user will need to properly aim and throw the ball so the receiver can catch it. If playing the receiver, the user will need to properly time and catch the ball thrown from the QB. The map should be simple, with turn and other elements that appear in a football stadium. The 3d graphics require human like player models that have simple rigging and animations. Physics for balls and player running must also be included. You may use any library for this implementation, but it must be contained within a single html script, and be able to be opened and played in the chrome browser.
