I recently purchased and installed STALKER - Shadows of Chernobyl. A little research demonstrated that community does not recommend to run this game without at least a basic, bug-fixing mod, but many also recommend use of Complete 2009. This fixes the same issues, but provides a graphical overhaul while aiming to keep the core play experience intact.
After playing the game for a bit, I decided to use this mod just for the added resolution. But I'm also aware a lot of fans claim the mod makes the game significantly easier. This seems to be a subjective opinion based on minor changes the mod makes to enemy awareness of the player which, in turn, was introduced to make stealth play a more viable option.
For all the arguments out there on this subject, it seems very hard to find out what, exactly the mod changes apart from the bugs, graphics and the added teleport system. Does anyone have a more detailed breakdown of what's been altered in terms of gameplay, why, and what the impact on the game is?
