It is also "bad" to not hire anybody. Very bad logic guys...
No, working with the guys you worked before can be a good thing in comparision.
Why does anybody get hired anywhere? Demand. There is a higher demand for output. This is very basic logic people. I am simply stating that the demand has went up.
You think too basic:
5 people to work on a game for 500 people is fine. 5 people to work on a game for a million people is not. Why? Because the funding went up, this isn't rocket science.
5 people to work on a game for a million is fine, too. That's also around the team size of Mojang (in the past) IIRC. Did you ever work in software development? If not please stop.
As others already said: With all that people playing Rust Garry was shocked. Right now facepuch is most likely dealing with that (anti-cheat, server issues, ...) so the money they get is the money they need cause they got it.
The critical, honest, and logical thinker puts 2 + 2 together.
Then please stop telling that the result is 5.
When a guy gets millions of dollars on a game that is in production and a million people are playing it... YOU USE THE MONEY ON THE GAME. I am not saying he isn't. I am not saying he won't. I am asking the question: Why not hire more people to work on the game?
Because it's not practical in any way. The team does a good job right now, why interrupt it (and as such interrupt anti-cheat, server issues, new content, ...). Also who says the money doesn't go to the devs? Maybe some 8hrs/week guy works 8hrs/day now? Also maybe they are licensing 3rd party software (cheatpunch came a bit too fast, did they really write it 100% from scratch?), rent more official servers to deal with the masses of players, do marketing, ...
All of your answers are on the level of a 5 yr old. If this is not as good as it gets for you guys showcasing your thinking skills, I fear for your future.
LOL
//EDIT:
Fixing errors and providing larger updates is two different things.
What about a large bug fix update? And fixing bugs can be way more work than adding new things. All the debugging, profiling, QA, ...
