I saw new game clan royale by clash of clan team. which is basically realtime player vs player. I Suggest RR2 make a game similar to that.
The plan would be very simple
make a new Royal revolt3 and import all of exisisting RR2 players accounts into them. Ie troops level and their health. and set some paths so their troops vs troops can fight. And obviousely hero should have some spells to use to make it more interesting Also no towers please. troops with elite boosts to have a lot of variation in between players would be great.
You can set wars at specific times
Basically its mini version of royal revolt2 but in a real time king vs king without much extra work
Hope you guys like this idea and make something like this
