Well, it is, compared to how incredibly large custom maps can be, but for casual gamers it would constitute an 'epic' experience.
This is the first "real" game I played - all the others before was just playing around. This one was played with the intent to win ... or at least play long enough to give some feedback.
Oh, and remember, this is from beta. Several new revisions since then.
Game 1:
Race: Humans
Difficulty: Normal
Scenario: Twelve Races
Version: Beta 2
The humans get a small bonus to research in every science field. This advantage is offset by their disorderly nature, meaning that they tend to complain and riot pretty fast. They start out in the upper right "edge" of the galaxy map, keeping the number of possibly hostile alien neighbours low.
All races start out with one well populated and somewhat developed home system and a couple of ships: 1 Scout, 3 corvettes, 5 transports and 3 Arks.
I immediatly grabbed the three better planets next to Earth, one ideal, one habitable and a barren but rich one. My home system started building 5 additional transports and after that a couple of corvettes. I also started building several research centers.
(Building several things simultanously doesn't slow down the construction speed of each item, so if you have enough production facilities, you can build several things at once.)
I transported colonists to the rich planet and kept doing so until the system could support a mine (for income) and two shipyards. The point of this was that production at rich planets is cheaper than elsewhere, so building two shipyards while ignoring the original one at the home system can save resourdes later on.
My research mainly focused on weapon and shield technology because I wanted the destroyers and cruisers - the one to kill, one to protect the killers.
To the "west" lurked the QuaQua which immediatly befriended me, offering me money so I wouldn't shoot at them. I took their money and shot at them, steamrolling over their pityful empire with a small fleet of corvettes and destroyers, which I researched and built just a few turns earlier. They were gone before turn 70 and their neighbours - the Xpectrada - were gone before 100. I barely bothered colonizing anymore ... I took what I needed and no one could stop me.
My empire prospered and I made contact with the Jellyfish-aliens, the AROM, the Klurgu, the Walden Forest and the Cryocon - all of which were only too happy to give me money for exchanging maps and/or not killing them. I didn't even have to ask.
Due to some defensive alliances I made (for cash), I got into several shootings anyway without damaging my reputation and my new Dreadnaughts were just awesome against their puny corvettes. I had a distinct weapon tech advantage at that time.
However, I was feeling the strain of fighting war on two or sometimes three fronts and my conquered subjects were not happy at all. The increased bureaucratic load didn't endear the public to me either. They barely paid their taxes - I suspect some of them ate my tax collectors - and I had to commit more and more resources into security buildings, weather stations, entertainment centers and whatnot - all in order to prevent them from burning down my security buildings, weather stations, entertainment centers and whatnot. That's the problem with conquered citizens as opposed to native population: They are not as happy as my iron fist would like them to be.
To make matters worse, attrition weakened my forces to the point where a sizable fleet of nearly 40 corvettes (yeah, they still didn't have anything better) nearly obliberated my main fleet ... and reinforcements took ages to arrive.
I realized I had to build some forward shipyards, but the conquered planets were either full of prisons and disneylands - or constantly rioting. That's when I decided to finally start building arks again to nurse a couple of rich planets into formidable shipyards and money makers. Of course, the previous owners had to go and I didn't bother with asking and eliminated the aliens that sat on good real estate. I guess you can say I made use of the fourth X.
However, getting the new planets up and running proved quite tedious and time consuming due to my strained finances and my recently destroyed transporter fleet. Without transports I couldn't shuffle population to the new colonies - and without population I couldn't build all the structures I wanted. In addition, even the new colonists of my own race think that burning down my buildings is a good pasttime ... I only have a few turns before they start to riot again ... barely time enough to erect entertainment centers and other things to improve their moot. Ok, their planets are a bit irradiated, but come on, they are RICH irradiated planets. Dropping marines and building security centers first to squash riots seemed like a better idea than appeasing those suckers - until I noticed that in addition to being unhappy with their environment they also felt surpressed, making them unhappy enough to burn down the security center.
By that time - turn 200 - I was number 1 in the universe. Largest empire, most victory points. But damn, I was a giant on clay feet.
That's when I shelfed this one game. I simply overstretched and mismanaged my colonies. And getting things sorted out was just too tedious ... and my enemies were surely building up their fleet while my decimated one couldn't get their reinforcements fast enough due to long supply lines and a strained budget.
All in all, a damn fun game even though I sucked.
