Endless Space does look like a good game. I am not a very active gamer tho but I do some to purge the brain. Following the link to wikipedia I see that I did play a 4X game once, long long ago and far far away .. Master of Orion. My son was bringing all kinds of stuff home in the day. While he was grounded for not studying because of too much gaming, I played.
So my only response to B) is Master of Orion as I can remember. I think it was a bit tedious tho. In the day, most of those were tedious. But, so is mahjong & just put it on the cell.
I would play this while I wait on things to run. On the other hand, if there is someone you feel more appreciative than I, by all means send it to them
