I made over $1mil with my 9 games on Steam, and I've been asked an interesting question: "is the majority of that revenue from a small number of very successful titles, or is the secret making a lot of them and it adds up?" The answer is how it is a bit of both. Personally I've never had a mega hit but I've definitely had a big gap between successful and unsuccessful games. I think my biggest hits were Game Corp DX which made about $250k and Blueprint Tycoon which made about $200k. So just those two made a big chunk of my total. But then the others, some made just $10k, others made $100k, so it varies quite a bit. In the end the fact that I have made so many games really helps smooth out the revenue curve. I'm a big fan of making small games and slowly increasing the baseline revenue. If I were not currently primarily focused on teaching that is exactly what I would be doing. Make and publish lots of small games to have a relatively smooth month to month income. FUN FACT: Even super old games still sell a handful every month. My first Steam Game, Survivor Squad, still pays me about one or two lunches every month, even though the game is over 10 years old!
