SUGGESTIONS FOR 2021 UPDATE:
Achievement Trophies: would be fun if i could get an achievement for killing a crew member in front of the other 8 members like an achievement calling me a "Big Fool". That would be hilarious.
Winning Points: would be great if we can purchase cheaper hats, pets or clothes for like 10,000 points or 30,000 points so that we cheapskates can do better in gameplays and win points. Winners get 500 points. Losers get 100 points. Quitters will get a deduction of -300 points. Having done all tasks will get an even more massive points like 750 points or 1,000 points. (This is me begging to try the ones i cannot buy coz i really am a cheapskate)
VIP Users: adding a luxurious skin like shining gold, white silver, ventablack, or PewDiePie-skin. New clothes that can support kinetic movement like ninja/shinobis from Naruto doing the Naruto Run, and/or floating midair like Goku from DBZ or in a magic carpet. For hats, a support in kinetic movement for burning skill like Ghost Rider, and/or dog/cat face. In addition, only exclusive for VIPs is Back Items like backpack, sachel, sword, or shield.
Hide And Seek Mode: since its popularity, the game became even more popular in hide and seek (although the most popular one was 99 vs 1) but even so, adding a new mode can change the pace of the game for it to become more than it was before, and not letting it die down faster than what happened to Rainbow Six Siege or the first declination of Minecraft before its reawakening. Adding other types of modes can be more fun than the achievements, so, i see this as an absolute win.
THAT IS ALL. NOT FORCING ANYONE ACCEPTING THIS OR ANYTHING. JUST A SUGGESTION.
