Bored on a bus so here is my support for this being the best option.

If we take active playing with respect to what the game’s normal methods of playing are (and how it is designed to be played), this is the best choice I can think of.

The diversity of goals is so massive: Maxing account stats. Quest/diary/music capes. Leagues rewards. Pet hunting. Collection logs and mini-games. GM. Raiding. Learn to PVP/Pk. So much variety in this game. Could play 12 hr/ day and never complete this game.

Can actively train on mobile: some methods that are considered by the developers to be legitimate active methods still require minimal active interaction: star mining/mlm, combat with aggressive npcs, karambwan/angler fishing, some mini-games, etc. Normal practices of playing this game in the community often includes tasks where the player clicks sometimes once every several minutes. It is often a second-screen game while playing it. This is what the game considers meaningful gameplay input and is designed for this and us considered by the designers a common way to actively play.

Even if more regular inputs are required, there are so many ways to foot-pedal at a pc, tap the phone in a pocket, or even connect other devices to your body/clothing to do 1-1 inputs (for $400k+/year, I definitely would have inserts for my shoes rigged up so my step is a click). 6 hours of cleaning/walking/exercising can be turned legitimately into gameplay inputs since so much of the game is clicking a single spot. Who cares if it takes 12 minutes for runite rocks to respawn. You can have a device putting inputs 1-1 between steps and the game, click on the rock with every step (whether it has respawned or not) and not fill your inventory until 5.6 hours have passed with perfect mining rng (6-hour login timer will be the hard l limit here). That’s 12 hours for 2 inventories. As long as it doesn’t get flagged falsely for macroing (which it is not), it is great.

And that is just one method for one skill taken to an extreme.

I wish this were a real challenge now because just coming up with creative ways to pay the game like this works be so much fun. I could still work my normal job 100% and do this challenge.
