I estimate between $40-50 million.

i`d say 12 million dollars

i doubt 60m, h3 cost 60m and bungie has alot more employees than guerrila.

maybe 30-40?

Lollatrooper.

It also wasn't in development as long, but my guess would be 40 to 50 without adding in all the ads, E3 events, etc.

A low cost top tier game (something in the top 25%) is going to run about 10 million for two years of development.

Killzone two probably at least had the triple that budget not counting advertising so lets say 30 million for two years. Add another three years onto the development times and it looks 75 million for the high end estimate.  If I were to say low, I would probably say 60 million.

Complete ballpark there but I wouldn't be surprised if it's the right ballpark.

@Twesterm thats using an engine thats already been built such as a proprietary or third party engine right?

@Squilliam: Gears of War says yes (I suppose you're thinking that too).

That's just a general cost, though a lot of studios actually use their own proprietary engine so I imagine engine work is included in that cost.  I doubt their engine was built entirely from scratch, they probably just improved upon their previous engine and built it specifically to work wit the PS3.

Building your own engine isn't that huge of a task (compared to everything else) if you're no planning on licensing it.

Yeah I was.

Twesterm, any chances you can tell us your thoughts about the game industry seeing as you're an insider with regards to development challenges?
