Basically Starscape is somewhat fun, and I played through it a long time before I got it on steam, then I played half through and the past days I finished it. The game has nice mechanics, but it is repetitive. The story could be interesting, but somehow isn't really in the end.
There are only 2 things which really bother me about it.
1: The resolution is limited to 800x600, which brings a lot of problems on newer hardware, and that resolution even bothered me way back then.
2: There are achievements for finishing the game on Easy, Normal and Hard. As opposed to common sense, finishing hard does not give the other 2 achievements as well, so you'd need 3 playthroughs to get all achievements, which is ridiculous.
If someone has endgame saves for easy and normal, please take a look at the discussion section of this game, it'd be cool to have thos 3 saves here so the achievements could be achieved properly.
So yeah, with those flaws and after all this time it's jut not worth 10€ anymore. If it's ever on sale again you might consider grabbing it if the points above don't put you off.
