I have an idea for a 'How the Grinch Stole Christmas' gamemode where it's basically like a 1 vs 'x amount of people' CTF gamemode and the flags are multiple presents, then there's the Whos who get various melee weapons and can move faster than the Grinch, and when the Grinch is killed, he drops the current flag and the Whos have to stand around it to reclaim it back to their town, which will take a long time to give the Grinch a change to retake the flag, unless multiple Whos are within range
The way it ends is if the Grinch can steal enough presents from the town, or if the Grinch runs out of time and Christmas is over, complete with an end camera showing Whoville and it's citizens positioned around a giant Christmas tree with a bunch of presents underneath, cheering and jumping
I don't have any good ideas for what equipment or exact stats the Grinch should have, so someone can fill in the blanks
