Endless Space, trust me I tried.
And I already played it so much that I usually cannot stand doing complete matches anymore. But theres something tranquil about the familiar and knowing exactly how the cogs turn and grind in the background. I certainly dont play it as much as I did in the past but I have such great memories from it, anger, frustration, overcoming my own imposed challenges, picking myself up after another crushing defeat at the hands of the AI, growing in both maturity and skill at the hands of the game and its community. The music is absolutely divine. The graphics might be dated by now but when it released there really were no better graphics and I probably see that mostly when I spot it in my steam library. It has been a great game for me and I tend to be loyal to things that treated me well in the past.
It never gets old to boot it up from time to time to start yet another empire, breed a searing
hate at the first AI daring to attack me and feeling the satisfaction to grind it to dust ignoring its desperate please for mercy

MUHAAAHAHAHAAAAA......errrr...sorry
