Good morning and hello from Cape Fear, North Carolina. I've spent many hours over the years playing Civ II and Civ IV; and have long been a lurker on this excellent website - until now as I find it necessary to ask for help. I'm 60 years old and know how to use a computer. In fact, I've been using them since the early 1970s; and was later a mainframe programmer analyst. I didn't get a PC until the mid '90s at which time I joined the internet. While my experience with games is not broad, I was a great fan of Zelda, and then Sim City; the latter of which led me into the world of using modded files. Now I'm on my third game "addiction" - the Civilization series; and quite befuddled by the application of modded files; because (a) the file structure is odd, and (b) the documentation by modders is often dreadful (if it exists at all.) Furthermore, as I read more and more threads where this problem is noted, there are scant few replies. The attitude of this website, unlike that of Sim City's, appears to be "if you don't know how to use modded files, tough luck." The above said, I have managed to apply some modifications to the game but the Blue Marble "mod" (or whatever it actually is) has my stymied to no end... I unzipped the file and placed it on my desktop. I try to execute it but get the message: "Sorry, Civilation IV installation not found. Do you want to search for it?" Clicking on "yes", I tried to make it work in a variety of places in "My Documents - My Games" with no success until finally I placed it inside the actual program file of Civ IV (something one would never do with Sim City) and finally it executed. But... Okay, it executed but left me staring at a box with several options to select. I let it stay at the default settings and looked for some way to complete the operation but there was nothing... The box just sat there; no button saying "complete" or anything else. I was left with no option but the click the small "x" in the top right corner which made the box close. Where the files went (assuming they actually did go anywhere,) I've no idea. And this done, I still can't find any way to make it work. And assuming files did go somewhere, how in the world would I remove them at a later date? The webpage for the Blue Marble mod is very fancy: http://www.civfanatics.net/bluemarble/content/index.php But where's the documentation on how to implement it? THERE'S NONE. Would it be too much trouble to include a "read me" file? Good grief! How the heck do we use it? Sorry for the long post - but I've wasted many hours trying to implement modded files here due to the extreme lack of documentation. It amazes me the length people will go to create excellent mods and custom assets - yet provide nothing in aiding use of their product. Yes - there's a learning curve - but why make it so difficult? Thank you.
