We’ve done this with several iterations in many threads. It will cost upwards of $600K minimum and require at least five or six people to design and test and validate and it would take 12 to 18 months. You can search the BBS and just the last year alone for a lot of this.
I think there’s a big difference between proving the engine supports two countries and converting the Main Arena to two countries. The WWI and AvA arenas don’t use the same strat system, reset logic, terrain layouts, scoring, or population balancing that the MA has been built around for over 20 years.
Looking at it as a business, not just coding, you’re probably talking 3,000–5,000 hours over 6–9 months with at least 4 people. A senior programmer, terrain developer, QA engineer, Dale leading the project, plus volunteer terrain builders converting and balancing maps. That doesn’t include community testing or post-release fixes. And that’s just to build it to get it finally validated and workable and all terrain and everything else is most likely double that.
At today’s market salaries, equipment, software, payroll burden, and overhead, I think you’re realistically in the $300,000–500,000 range just to execute the project. If you had to truly rebuild a small studio around it instead of one guy working from home, I don’t think approaching $1 million is nearly as far-fetched as people might think.
Please just enjoy what we have until we don’t have it anymore.
