I'm kinda bored honestly, and i have free time so i decided to ask here.
A multiple-choice realistic game where it's just footage of two actors talking over headphones / voice chat, and you have multiple choices for dialogue and dialogue is text. Depending on those choices, anything can happen - from the two staying in their respective houses, to road trips, to the two helping each other out in life, and being with each other as friends through big events - weddings when they find and end up marrying their respective spouses, etc.
Shooter game (top down, 3D or sidescroller) in which your shots depend on your HP. With full HP, your shots are single and deal regular damage. With half HP, your shots are single but deal more damage. With critical HP, your shots are triple, deal regular damage but each shot which hit something drops health.
