I haven't started a videogame company, but I did look into it seriously at one point. What stopped me was the financials: it looked like I would have needed a fairly sizable hit (by the standards of the time: before the iPhone and AppStore) in order to cover my costs. The picture has changed quite a bit since then but my advice would still be to have a good think about the money before you take any irrevocable decisions.
In particular, figure out how many sales you'd need to cover your costs; then do some market size estimates to figure out whether it's realistic to hope for that many sales. Don't forget about cash-flow either because it may take a while for your game to start selling, sales may tail off quicker than you anticipate, etc. Use that info to help decide whether it's a risk you should take.
