Entering subjective mode. Everything I say I based upon my experiences and analysis. I have no inside info and could be wrong:
It’s the production and post-production issues. Brave Soul had more patches than any of their other products and these patches were pure bugfixes. Only a couple other games that’s had a pure bugfix patches and those only 1. Brave Soul did break records for PP in terms of sales, but getting it to work, from what I’ve read and based upon the number and type of patches, wasn’t easy. Fan translations, like CF2R do not have to deal with that because they are simply doing a translation and do not tamper with the engine generally. If someone complains about the game not working because of the engine, they have no reason to fix that because they aren’t out anything. PP does because that person could give them negative publicity which could hurt sales of future products down the line and for niche markets that does matter.
