Are you guys ever not able to decide what game you want to play too?
I got an idea for how I can help fix that whenever I have that issue, but note this only works for games that have a character level system, world level system, or progression system of any kind. The example games I'm using for this post are Cookie Run Kingdom and Adopt Me, by the way.
Put the games in an order. The order doesn't matter. Remember how I said this only works with games that have some kind of level system or progression system? What you'll do is set a game progression goal you have to reach for each game. When you reach it, you move onto the next game.
For my examples, I would make it so in Cookie Run Kingdom I have to reach and finish whatever the next level is that completes a quest, and for Adopt Me I would make it so I have to age up a pet once (only half-way for post-teen)
