Couple of ideas that most likely wont see the light of day

or will it?

Wolf Winter: set on the eastern front of WWI, Russian and German soldiers band together to fight off the packs of wolves that feed on the dead and wounded, becoming bold enough to attack humans with increasing ferocity. Based on a true event but we'll add in WEREWOLVES. Also thought it'd be fun to write dialogue in English only because that happens to be the only language our two MCs have in common.

Undercover Lich:
Lich get's sick and tired of adventurers trying to off her, decides to masquerade as a cursed adventurer with a TragicBackstory and go undercover to see what the big deal is. Eventually learns the power of friendship, extreme violence and the realisation that holy fuck she hasnt been "brooding in her lichtower", she's just been DEPRESSED.
Bit of the done to death isekai undercover overpowered character schtick but with the added twist that I wont fucking ruin it with video game isekai dumbfuckery.
