Galaxy disappointed me. Most of the game felt as if it was made for a nine year old, and there was lack of challenge throughout the game. I like to play games that have some sort of challenge to it, instead of this mellow, easy stuff.
The planetary system, each tiny individual planet with it's own gravitational pull, got really annoying. I felt a good urge to play on a large flat space, but I couldn't.
I think this is very much overrated.
