My wife and I might retire in our mid-30s, in the US but not in an expensive area, and be completely comfortable with well under $1 million in assets. Because we live a laid back, low cost lifestyle -- with the house paid off (as of this week) our burn rate is dropping to under $20k per year.
You might need considerably more money to maintain your desired lifestyle. There's nothing wrong with that -- but recognize that not everyone is you.
raise the kids. Make indie games, with the understanding that it doesn't matter if they never make significant revenue. Write. Read. Study. The key point here is really "not needing to earn more money" rather than "not doing anything".
