It used to be a lot more viable to publish a multiplayer title and have a good player base. Nowadays, player bases have been captured by large live service models. Games like tremulous where you essentially play as an alien ant and gain points by building buildings and killing human soldiers to evolve into a bigger aliens. There was also the human Marine team who basically played like starcraft Marines.

It was essentially first person team-based starcraft. And it was amazing. And nobody’s playing this shit anymore. It’s kind of a shame.
