Yeah, I know, the mapping is really bad. I had to cherry-pick the best maps in the game to pass the minimum mapping criteria for the site (and the mod approving it was fully aware I was doing that, though).
I had considered the idea of remaking this game with improved mapping / etc, but now I'm leaning more towards just making something entirely new, basing the gameplay (but not story, mapping, etc) off this game - since the gameplay (at least in battle) is the one thing this game definitely does right.
