Hi!

I'm a Civ4 player, and while I was browsing on CivFanatics.com
WWW Link, in the forum section Other Games, I've found the Galactic Civilization II game. I suddenly got interested and searched game info. After reading the GalCiv2Wiki, after downloading and playing the Demo and after viewing some cool ship designs in the CivFanaticsCenter (aka CFC), I ended up in this forum and registered!
I want to buy this game but I want to make some questions clear.
If anyone out there plays Civ (better Civ4, even better Civ4 Beyond the Sword (aka BtS) and yet even better, also posts on CivFanatics (of course such 'perfection' isn't needed!

)), can tell me the major and bigger differences between Civilization 4 and Galactic Civilization II, I would really appreciate it!
1. If anyone knows the difference between this game and Civ4 BtS' mod Final Frontier (aka FF), please answer them to me!
Don't tell me basic stuff like "there are aliens in this game", "some planets are inhabitable in this game" or "there are no supernovas or black-holes in this game"; I also know the basics!
(BTW, there a demo of Civ4 BtS where the player can play the first 100 turns of FF; though in that version it was a few errors, and you're always playing in the same map with the same civ against the same civs, it worths to try! (in BtS full version you can even choose the star system density and other cool stuff!)
See the download mirrors in this CFC's thread:
WWW Link(BTW, ThunderFall is our Administrator and Jon Shafer is the FF creator/modder)
2. Do I need the Dread Lords to play the Twilight of Arnor like I need Civ4 to play BtS?
3. Can I play/buy it in an 'ordinary' CD? It's because my brother right next to me will also play it in his computer, and following your rules, if I do that, I wouldn't be able to patch at least one of the computers. Can I, with an 'ordinary' CD, use the method I use with all other games (like Civ4, for example) that consists in putting the CD in the drive, run it, remove it, put it in my brother's drive, run it, remove it and putting it back in my computer's drive again (with everything just working fine)?
4. Can I play alone (with no AIs or human players)? And infinitively (with no victories allowed / till I get bored)?
5. What's it's price? Do you guarantee me if I buy it here instead of in E-Bay or any other website; it will be cheaper here?
6. Can I create a Map? And edit one? And change it in mid of a game with immediate changes?
(Civ4 allows every of it, with the World Builder (aka WB)! )
PS: It won't hurt no one of you to also post in the
WWW Link (CivFanaticsForums aka CFF) forum! It's a great community! (BTW, I'm GarbageinHere)
And one more thing: CivFanatics rocks!!!

Off-Topic: Your forum needs greatly improvement! There's no 'Avatar List', no 'Preview Post' (mine is "disabled", why?) and no 'WYSIWYG feature (aka WhatYouSeeIsWhatYouGet)' ?!?
