Dungeons and Dragons

I similarly remember lots of pizza and chip snacks with soda in my youth, but these days it's often hummus and crudite and beer or wine. Though the DM has asked us to wait until the session feels half over before uncorking the wine...

We functionally switched to stuff that won't muck up sheets or dice. Also, as a group in our 30's and 40's, more people have various dietary concerns, so veggies and bean dips help solve a lot of that.

The DM and I love to cook, so sometimes we'll make themed dinners. Roasted, spiced mushrooms and asparagus and a kale salad for when we stayed with the druids, beer, bread and root veg for a Dwarven section of the campaign, grilled fish (that I caught earlier that day) when we started at a port village, that kinda thing.

Saw a post a long time ago about someone using gummy worms and bears etc as their minis, and players get to eat the ones they kill.

Food for thought. Literally.

My main crew typically goes with vodka and sushi on our biweekly session.

When we have a younger/new player we go with seltzer and mixed veg/fruit/nuts.

Soda or another liquid that is bad for me. For food, I was generally in charge of food so if I made food, it was themed! I have the Song of Ice and Fire cookbook, and when we played that system I made food from there.

Our table always drinks coffee during a session regardless of time of day. As for snacks, whatever looks appealing from the local dollar store.

Cheese balls. Giant tubs of cheese balls.

Twix dipped in Fritos chile cheese dip.

Often snacks like chips n dip, dinner varies, pizza or some of us will cook a stew or something. Most often we have beer or seltzer water. But we're all in our 30s.

Sweet, Salty, Savory. It's a winning combo. I'd keep drinks as a BYOD situation, aside from maybe having one or two 2 liters of soda or something.

Roleplaying whiskey. Its just a bottle of whiskey that we all drink when we play

One of the perks of being older is we smoke or bbq to have a meal prior to the session. We've had brisket, chili, smash burgers, tri tip, brats, etc.

Chex mix is a classic!

Online VTT player: I usually don't eat when playing, almost always have a beer/wine/G&T.

I don't like trash food and I don't drink energy drinks (only water), but I enjoy taking a food break during sessions, mostly because it allows me to stand up, stretch a bit and go take whatever I may want to eat that day, which improves my attention span in the second half of the session.

Sometimes it's some fruits, others it's a pack of potato chips or just a cup of coffee. During winter I'll most certainly toast some bread with cheese and salumi, to keep myself warm!

I'm Italian, so it's not difficult for me to buy brands that use high quality ingredients and are still fairly cheap to buy. And if the session stretches through dinner, it's pizza time for everyone! Although it's been a while since I last played a session in person, because my party is scattered all over the country, forcing us to meet online.

The game I run is virtual and only 2hr so just water, sometimes alcohol.

The game I play in provides dinner ahead of time and I often make a dessert for the table.

We mostly drink beer or shandy, and we use caps as minis, you can have multiple colors for teams and write letters/numbers inside to identify them But it requires to drink before any fight happens, so we always keep some stored from previous session, just in case For the food, thins that can easily be shared so pizzas like you mention, crepes, or raclette in winter

Cherries!

@TheGiantKorean I create infusions of fruits and plants in various alcohols, which we use as potions in small flasks, distributed with absolute parsimony for a lot of gold pieces.
