" I've even got a business consultant (my ex-gf. Eek!) to help me out."
Were the first words out of her mouth "You will never make money on this"? By no means is that meant as a put-down, just trying to help set appropriate expectations.
The market is flooded with tiny, good quality games journalism with great histories that are endlessly broke. Then you've got the mega-conglomerates putting out exceptionally poor journalism, and even they barely scrape by, constantly under threat of closure or sale by their old-media owner.
If you're doing this for the love of it with no expectation of an income off of it, then more power to you. If you are doing this as a business with intent to make money, then you need to throw your journalistic integrity out the window right now in order to have any hopes of success. In that case, I hope you don't go any further. We have enough ridiculously poor quality journalism in this industry as it is.
To answer your survey: Look to No High Scores, Penny Arcade Report, Kyle Orland over at Ars, Colony Of Gamers, and RPS for who you should finding inspiration from. Look at Evil Avatar, Kotaku, IGN, and Gamespot to see what is wrong with this industry. Focus on creating original content. Do not stick a score at the end of your reviews. You have no chance of success covering console games, so don't. Instead, skate to where the puck is going by reviewing and reporting on mobile games and indie titles likely to show up in a Humble Bundle. Read the http://gamejournos.com
