So, Tabletop RPGs are some of my favorite things and some of my favorite pastimes. However, like any endeavor, burn out is very possible.
When this happens, I used to take a step back and focus on other stuff for a while so I could relax, but that just left me with a lot of free time spent vegging out in front of a TV or a computer, which didn't really help.
Now what I try to do is to learn about a different system. I tried that after being very frustrated with a player, and it helped me not only reverse the burnout, but also helped me find a way to finish a dead end adventure.
I try my best to learn about ones vastly different than what I usually do.
I play Medieval High Fantasy? I shoot for Grim Dark Sci-Fi. I get done with that? I go for 1920s Call of Cthulhu. I normally go for the d20 System? I go to d10s, Fate, or percentile!
I change it up and learn about the lore, since it can be very good for inspiration!
Warhammer 40K has amazing Space Orcs! I've devised a silly adventure from them for a one-shot based on it! It's a great way I've learned to reset everything.
I'm aware that not everyone is as fanatical about these games and wants to learn all this stuff, but I thought I would share in case someone else might be able to use it.
