Yeah, if youre talking about big graphics and physics obsessed games, corporations dominate and push everyone out due to their sheer scale. In a communist society, I could see these games made through large open source effort and recycling of much of that effort so a game can be made without having to completely re-invent everything for every game. I could picture open source game engines which many people work on, made freely available for use, and many different games with many different stories being made on the same engine. So for example a medieval fantasy game like Skyrim, a futuristic cyberpunk type game, and a modern crime game like GTA all being made on the same engine, with game makers focusing more on story and theme specific graphics and models, as opposed to every new game having to re-invent how light works and how to make a person walk. Almost like how modding works today to radically transform some games from their original premise, but with game engines akin to complete games that are intentionally empty, but very malleable. Someone who wants to tell a story through games can pick a suitable engine and create within it as if modding a game.

Closest thing to this I think currently existd is Roblox, but imagine it not a complete meme and cashgrab.
