LANCER is absolutely a vibe and I enjoy very much.
I think my favorite system to run is LUMEN especially with groups that want the freedom to do the coolest thing. I mostly end up running D&D 5e and I’m very tired of being the rules lawyer/ loremaster/ combat manager/ etc.
Rules-light systems like LUMEN actually give my players a chance to get what they want while still paying the cost in resources, with a touch of tactical combat that made a memorable game.
Also a fan of Kids on Bikes, and the exploding dice mechanic from games like Savage Worlds!
Typically my own allergies compounds with dust allergies, so cleaning where I can and using an air purifier tend to help. Otherwise, I like getting some local honey; supposedly the pollen its made from helps your system (I’m not sure how much proof there is, but I still stand by it)
Otherwise, a warm honey lemon tea is always good for the throat/ sinuses if your allergies get uncomfortable.
