well since so many are requesting random events I'll add them for sure on next update.
What you mean if the technology was slightly different every time you played? I don't understand this part
I based the game on classic technology development trees like Civilization: you have to research first the basic stuff and then build the advanced one. There is some variations in the full version since you have the Alien Technologies that are different from one side to the other, and also they start randomly placed on different stars every time you play the game.
I'll add the random events, but also make the change requested by wolfdaddy, that is the custom ship building. Right now, if you want to discover a particular ship like the interceptor you need to research certain technologies. Instead if you can customize the ship equipment, you could even use the interceptor blueprint and place on it 5 long-range bolt, so that you don't need to research the missiles/torpedoes. (maybe this is what you mean for different technology)
I think this simple variation could change completely (in a much better way) the game, and that's what I'm going to do next, together with a skirmish mode that will be available even in the demo (with some limitation) so people can play the battles, which I think is the main focus of the game. Right now isn't really a "space strategy/colonization game", but more a wargame with a resource management backbone. Indeed as someone else posted here the game is way more similar to the SSI game Star General than Master of Orion series.
Hope I managed to solve some of your doubts about buying the game
in any case remember that, as happened with my past games, I'll continuously add improvements so in 4-5 months you could end up having a completely different (better) games from today.
I might also consider allowing more playing time in the demo.
