Weighted Wildlife. They specify how much each one weighs on their site. I have an opossum from them and I love her. She’s one of my favorite plushies (don’t tell the others I said that though). They’ve also got some 5lbs dragons in the works.
Creep Cat Toy Company also makes some weighted plushies like the raccoon and opossum, and the weighted ones come with a zipper in the belly so you can, remove, or move the weighted bean bags around.
Do it on the clock, during a work day. Make sure you plan for nothing to get done that day. Make it optional: go to the field trip (expenses paid), or take a free day of PTO. Either way they get paid and, because you planned for it in the development schedule, don’t have to worry about potentially having to play catch up because of the day off later. That way it gives them the choice to go do something fun on the company’s dime or stay at home and recharge. Another thing to note: don’t limit yourself to game-related stuff like video game museums.
Go to an aquarium.
Go to a zoo.
Go to a national park if there’s one nearby.
Go to a natural science museum.
The artistic side of game dev takes inspiration from a wide variety of sources, not just other forms of media. Tbh, the most boring field trip I can think of would be to go to a movie theater or video game museum. I want to see something new and take inspiration from that.
