I don't think the current rookie would even remotely suffice for a steam release.
The first thing you default to, as a new player, is use the rookie in battle. You meet anyone's bot and you get absolutely crushed. It uses like 600 cpu, and then another 200 on landmines, and a lot of it's design that does exist is a bit questionable on the whole.
The new rookie should have at least 1300-1500 cpu used on the main bot. I have already submitted a potential rookie in #║showcase message but i understand it might not be the best either for one reason or another
