The second aspect of the game that you see is that it begins in medias res, and the bulk of The Orion Agenda plays through the events leading up to that beginning point. This particular literary device can be tricky to incorporate into IF; in this case, I managed to get myself killed twice during the "flashback" portion of the game and there was no attempt to resolve the discrepancy.

Third, you will probably come to realize that the "number one rule of SciCorps" sounds an awful lot like Star Trek's Federation prime directive of first contact: no contamination of undeveloped worlds. Some players may hold this against the game. I did not, since it's a concept that surely has been explored outside of Trek (and possibly before Star Trek made the idea well-known). Much of the plot and puzzles are related, at least tangentially, to this rule.

The game incorporated its puzzles into the environment fairly well. However, the driving force behind them was pretty transparent, making them partially feel like puzzles for puzzles' sake. And while the descriptions and plot were done well enough, I found a lot of the dialog to fall somewhat flat and unreal. The conversations with the old Orionion (I can't stress enough what a poor choice of species name that is) were particularly jarring, especially with the stream of insults he tossed my way. I suppose he was supposed to seem endearingly grumpy, but writing a character like that is tricky because after a while you start to wonder if the insults are coming from the character or the author.
