My friend had told me ages ago the RE creator had made the entire Biohazard on psx with only 10k usd, to me that was definitely bs, so i've been trying to find any data about it to show him about the true numbers but i can't find anything about it, now i'm curious af to find out the budget of the first RE back in the 90s, the best data with source i found was the cost to port RE2 to the N64, the port alone cost to capcom 1 million usd. i'm really curious to find out, my guesstimations for this title were always something around 1 million, so the 10k usd thing really made me curious about the numbers.

  Does anyone have any idea or source with the estimated costs for the first resident evil on psx?

Your friend is wrong. If that is the end result you're looking for than there you go. Resident Evil was considered cutting edge during its release and took 4 years to develop(iirc) with a huge team. Are you sure he didn't mean 10 million?

"The project's development began in 1993, and the game took three years to develop."

You couldn't even hire just one person for more than 6 months for $10k. Needless to say the production cost was many many times bigger than $10k 

 Where did you get the number from? guesstimation?

Street Fighter II cost $2.45 million, so there's no way that Resident Evil was only 10k.

Did your friend honestly think it cost 10k?..

Wow.

  Yes lol, the lowest i ever thought it would be is like 1mil, when he said 10k i was like, wtf. Resident Evil one might sound low budget cause of the amateur live action cutscenes and dialogues but the game itself already looks way better than any other psx title released in the same time frame.
