A team-based, most likely top-down sportlike game where the objective is something sportsy like kicking a ball through one side of the field or putting it through a hoop to score more sports points than the other team's sports, but half of each team is AI-controlled and nobody has any names, making it difficult to identify who's a player and who's a bot. What everyone does have is the ability to possess another character aside from themselves and control both at the same time via separate ends of the keyboard, which would be done to intercept positions, coordinate between two characters more effectively, imbalance the team numbers in your favour, and so on. Teams would be small - 4 to 8 or 6 to 10 - and controls would be simple to accomodate this, but the twist is that if you attempt to possess a human player, the two of you swap places and teams, meaning you might now be on the losing team - so losing team players are more likely to be possession-happy than the winning ones, at least until they swap roles. If someone possesses a bot you've already possessed, the control goes to them and your possession is locked out for a short time, making identifying player mannerisms and correctly guessing their controlled bot to be rewarding.The first person to get the most sports points in whatever sport the map is imitating wins, similar to real life sports, but with the souls of the damned wailing around the field and into players.
