eric5h5: Still using the same 32-bit engine that's been used since the beginning, so no. Maybe time to get a little modernized, or even break out a little and do some different games? I have three of them and they're pretty decent, but 15 years of the same thing over and over with relatively minor tweaks starts to get old. Even Drox Operative isn't as different from the dungeon crawlers as it appears at first.
So it is the same engine. Which means the game is more an expansion, or a different approach on how it handles it.
I know if you look under the hood at the files to edit them there's tons of references to their other game Din's curse. And yes it isn't much different from a dungeon crawler, the difference being if there's walls or not, otherwise there's levels, quests, items, damage resurrection experience, a few cosmetic changes and it's basically the same system with a different coat of paint. Similarities stood out heavily before, though it was unique enough you more or less chalked it up to the difference of playing D20 Fantasy vs D20 modern or D20 StarWars or similar.
I'm sure if he shared the source for the engine people would patch it to be compatible with mac, although not sure about IOS since Apple seems determined to keep pushing updates to break everything.
