This is Version 1.5, READ the description, it provides information about what has changed since the LITE and PURE versions of the game and what you should expect this time.
The Master Edition increases the difficulty of the games trading system, and various item effectiveness as well like medical supplies. Prices have been multiplied massively, but don't be alarmed, I have changed the base prices of all equipment in the config files so that you will be offered more money for what you sell based off a realistic percentage profit from all the traders. You are supposed to make choices in this version, save up for items that you really want, do not blow money on something unless it is otherwise difficult to find or too far into the game. Other things you should know: Duty and Freedom are now included, I had to adjust them to balance the mod better. Also, Freedom will sell the unique SVDm2 to you IF you do all their quests for them, Duty will sell you the unique Tunder assault rifle IF you do their quests instead. Factions (including the ecologists) will also no longer buy and sell items that they do not use in the game, this makes them more unique to add realism. Regular NPC trading has also been adjusted to balance the game as well, they sell medical supplies and food for MUCH more than normal traders do, this is to make them feel more like harsh and cold bastards. Also, in this version there is only a chance of items being available, unlike the other two versions where there is a 100% chance of every item being up for sale at all times, so check back in once in a while to see if anything new is up for sale. Lastly, medkits, bandages, and anti-rads have been nerfed to drastically boost the difficulty of the gameplay as a whole. Enjoy!
If you are seriously lame enough NOT to play the "MASTER" Edition of my mod on MASTER DIFFICULTY then you are being an idiot, and are doing nothing but shooting yourself in the foot. This was MADE TO BE PLAYED ON MASTER DIFFICULTY.
