A question that's been bugging me for a while was: how come nobody's made Ender's Game: the game?
i was messing around with the variables and by removing the gravity (or setting it very low) and setting the /aircurbforce var really high I could get a sort of Battle School-like style of combat. (for those who haven't read Ender's Game, Battle School is where child prodigies go to train for a war against aliens, and it revolves around a zero-gravity battle room where teams of kids fight fake wars that can get a bit too real sometimes.)
My idea was a sort U-shaped arena where both teams start at the top(becuase the enemy's gate has to be down for both sides) and there are crates floating in these rooms. Players have to make their way down, then make their way up by kicking off walls and crates to get to the enemy's flag. I haven't seen too many vertical maps, but I think with these settings it could work.
feel free to add on to this idea.
