A monthly Leaderboard could be interesting, but if you really enjoy a game and are motivated to try and get on the Leaderboard it is possible. I understand it would be harder than other times, however that is how Leaderboards works, you compete to secure a spot then others follow and try to replace your position. A monthly Leaderboard overall about how many kills or wins someone has in a certain time, in all the games, could be an interesting concept. I prefer the Leaderboard system like it is now, due to the sole factor you have to work very hard for it.
The addition of parkour would be a nice game for Bedrock. It could become another simple game to chill, which is somewhat hard to find in Bedrock due to majority of them being PVP based.
Can you also add a poll, so people can vote on this?
