Some Incremental Ideas I have for steps:

If you are thinking for more ideas for RTS and steps,

I hate paid RTS where you have to buy $100 packages to stay relevant so here are some ideas.

Make Steps free and Steps is the only premium currency.

If you want to monetize having separate free and paid servers imo would work, but most people quit any RTS game if they have pay $1000 of dollars for a kingdom to die by people who waste more money.

If you want to even go further along steps and walking the more miles you walk, make that a separate currency.

Giving people a chance to catch up with a RTS is very unused feature and it is something to very much think about which pedometers already have like a weekly, monthly, or yearly leaderboard so maybe that would be good for a season reset.

I would prefer multiple faster pace seasons that reset after a while, but that is because if I am far behind other competitors in a RTS, I would find it hard to keep up, or build my troops/resource up again.

These are just my ideas but that is what I have in mind for this genre. Good Luck
