P.S. Of course, fully 3-D graphics would be computationally expensive since you can have hundreds of units in a single battle. However, there may be some unique opportunities for optimization by pre-computation and caching, since the battle is completely deterministic. (Also, of course, optimization by sharing between units of the same type, since almost no battle would have hundreds of types of units.) It would be an interesting challenge in graphics programming.
