You can 100% do that with quantized models that are 8b and below. Take a look at ollama to experiment. For incorporating in a game I would probably use llama.cp

The game itself is not going to have much VRAM to work with though on older GPUs. Unless you use something fairly tiny like phi3-mini. There are a lot more options if you can establish that the user has a 3090 or 4090.
