This here is the Text Improvement Project (T.I.P.), I call it that because I think S.T.A.L.K.E.R. needs more dots, anyway, my goal for this project is to one day rewrite all the PDA entries which are still Google Translate into fun to read pieces, it will take a while, meanwhile enjoy the text gradually improving.
(Update on progress: This project is not dead, I just won't be updating it for some while as I'm reworking it and it's going to be part of another project. If after this there's still need for the T.I.P. on it's own I will update it. If you really badly want to have regular updates let me know and I might consider it, else just give me time to get everything done nicely, with some luck it's going to be worth the wait, anyway, thanks for the downloads and comments so far, I'm happy to work on this and be part of this community!)
Here is version 0.3 with more updated and improved texts, at this point 10 out of 33 texts of the arc_string_table file are rewritten. Check the included readme to see which ones exactly.
Feedback and suggestions are always welcome and will only help make the text better. Enjoy and good hunting Stalker!
Make a backup of the files involved or your whole gamedata folder, or not, up to you, things might break though, probably not, just warning you.
Unpack the archive and copy the gamedata folder into your main game folder. Overwrite when asked.
