When it comes right down to it, X-Com: UFO Defense and Master of Orion II are basically the gold standards in both their franchises and genres. Master of Orion 2 is really the only 4X game that I've truly enjoyed as much as it, it's also always had a place on my hard drive, on every computer capable of running it that I've owned since the game came out. MOO2 is nearly flawless in 4X execution, it's extremely well balanced, the AI is fairly smart, and you can turn off parts of the game you hate.
All said it looks like the new Master of Orion changed the formula too much to be as good as 2 was... Which is a shame.

I just finished Master of Orion 2 for the first time, I wouldn't say it's perfect. Every other time I've tried to win the game I got bogged down in battles with dozens if not hundreds of mediocre alien ships that seem to take at least half an hour a turn, until I eventually gave up.
You can always turn off tactical combat... You're aware of that right? Just like how you can turn off random events to avoid those nasty hyperspace fluxes, or you can make your race repulsive to not deal with diplomacy.
