I have some 150 hours in the game and while I had some issues with crashes in the beginning, a couple of patches ago, they went away and I could play without technical problems.
What I _do_ have some issues with is, that the game is obviously made with the idea to turn a _lot_ of stuff over to automation - which I wouldn't have a problem with, if there were the tools to switch to manual and do it myself (every strategy gamer knows that when you turn something over to the AI that you could do yourself, you're screwed) - but those tools simply aren't there.
You can't set waypoints for your ships/fleets _and_ you can't que up orders _and_ you don't get a message when a ship/fleet completes it's current order - which means that by early to mid game, I have to check my ~30 explorers constantly to see, if some of them have finished their current task, check if my fleets have finished fueling up or have arrived at their staging area or if one of my ~15 construction ships has completed it's order to build that new mining base.
There are also some things you can't turn off by default (well, at least I haven't found a way to do it), like the resource reserves for mining bases, which by default will demand fuel to be stored in them. I guess they are meant as refueling points for your ships - which would be fine for those bases that are above a gas giant and are actually _mining_ fuel, but having several 1000 units of fuel in every single of my 100+ mining bases means that my shipyards are dry as the Sahara desert and while I _can_ turn the automated resource levels off and set fuel to 0, there is no way to do that globally, so I have to go through every single base, switch automatic to manual and then set the reserve level to 0 - and since you don't get a message when a new base is completed, I have to do this again and again and again.
Don't get me wrong, I still like the game (I wouldn't have 150+ hours in it otherwise), but it can get rather frustrating at times.
