[Griefor]

While converting the entire application to multicore might be a huge amount of work, I'd think that converting just the battle resolution (which is the only thing that takes a lot of time anyway) shouldn't be that hard. As long as you know what you're doing (this is probably not a good first attempt at multicore usage) and the battle resolution is programmed the right way in the current state.

I mean, think about it. Every turn there is a bunch of battles, and they're all mostly independent from each other. The flow of the program might have to be changed somewhat ( prepare all battles first, then resolve them all), but the subsequent multitasking is basically just resolving multiple battles at the same time rather than one at a time.
