cassete beasts is a pokemon-like game, that wont require to much power.
ember knights is very simmiliar to hades, both are great roguelikes.
doom2, blood, duke nukem 3d etc run with low power consumption.
a hat in time is a 3d jump n run that can ve limitted to 10 watt tdp (maybe less)
what is a hero shooter and what makes it overwatch-style?
I’d think tf2 would be one.
