@yue123.
Your ignoring too many factors.
1) did they build up brand name ?
2) did they benefit from making othergames easier to devlop ( eg. Resistance engine was improved and then used as a cheap engie for Rachet ... and will be used again for resistance 2 -> making each game cheaper and cheaper to make)
3) How much profit were they expecting ?
4) Are you sure they need 400k to break even ....
5) a 25% of cost returned as profit is excellent! Its these small title with good profit which keeps the company going inbetween the blockbusters ...
