Now I'm just throwing oddball versions out there. One is fantasy like, And the other is not emergency response related at all but most likely could be worth for Sebastian looking into later on down the line once Missionchief and it's current counterpart versions are good to go or are good for the most part.
1. -Post Apocalyptic World Version- Zombie missions. Like Resident Evil, The last of us, Dawn of the dead etc. Having all three emergency services plus national guard or military of some sort or a civilian militia giving new groups for the game. Same basic format as it is in this game, but with a zombie like twist. Or an Alien like invasion such as Independence Day.
2. -A Military Version of Missionchief- Allowing players to build military bases on the game. Simulated missions and allowing players to ship to other countries based on the missions. Not talking about any PVP type gameplay. Just solo players or Alliances fighting simulated missions with all five current branches and possibly this new Space Force branch. This one may be a better look into than the first idea brought up.
Just a couple ideas to possibly further the future of Missionchief God forbid Missionchief dies down any. Hopefully that's not that case of course.
-America's Most Wanted- And my other idea is having wanted criminal missions pop up out of the blue. Like America's Most Wanted, If the mission pops up you will only have a strict response time to get to that mission point and if you win you could get a random reward. Could be 500 Credits, Could be 10,000 Credits, Could even be 20 Coins or so. Makes players interested to play more and stay focused. This mission would pop up once a day or every other day and you wouldn't know it until it pops up. Or could be one of those checkpoint missions with a time limit and only giving you so much time to respond to.
-Daily Activity Rewards- Another idea is daily activity rewards. Each day you are onlube playing you get credits or a small amount of coins for being on Missionchief. I don't see this as a way of cheating cause if you get on just to get the reward you can't give it to someone else, it just stays in your account. This one also gives players the motion to want to play more often as well and if by some chance you miss a day then you will have to restart your activity rewards.
-Daily Chance - Each day you get on you click to spin the wheel and get some sort of random reward.
