Money
I know that it is an obstacle but I'm Talking about success projects(I mean a project that give a good amount of revenue achieved an player base community and can stand in the market)as long as you invest the money in good way you get more profit.
Control
I Agree working alone make decisions fast since you are the manager/project manager/programmers/etc.. at the same time but that doesn't mean it's the right decision you could be wrong but you won't know cause no one told you "No" and with a team each member will take role
and do it's job without interfering with other members, Yes it may slow down the game progress but at least it will improve quality.
Empire Building
this is what I'm talking about I'm kind of guys i want to success and grow more for bigger success example: currently my target is to have 100 followers Next 200 Next 500 etc... and in future release on steam, not an easy task but i want to build myself an empire
Career choice
Again agree, Mainly i like programming and problem solving if i have a team it's not necessary to sit back and work as the manager only i can be the Programmer and the manager. Managing people is hard especially if you have lack of communication or others working remotely and for the game progress Set a Deadline having one is better than not having it.
As for money to keep the Studio sustain itself you can make a contract with a Publishers or be honest with your employee and tell them that this is not working well and layoff before going bankrupt(it might depend on the contract between you and them).
This is my personal perspective correct me if I'm wrong
