I'm worried that if/when you DO switch to the latest RenPy version it will mean that 32-bit Windows will no longer be supported, as that's what I'm using. I feel that unless there's some compelling reason to upgrade to RenPy version 8, then existing games should stick with the previous version. It's a different matter with new games, where there aren't players who have been playing the 32-bit version for a long time. (Yes, I know very few people are still using 32-bit Windows, but I can't be the only one.)
