The Elysium Enigma

This XYZZY-award-winning TADS game shows off a lot of the power of the engine, like tracking what the sense can detect and from how far away.

You play as an officer in an Empire of planets, sent to check on a small backwater. Your goal is to talk with the local technophobic elders and leave. While there, though, you meet a strange, disingenuous but beautiful woman.

I like quite a few of Eric Eve's games, which tend to be very polished, have highly interactive characters, and fun puzzles. All of his games tend to have attractive women who either already know you and are attracted to you or just met you and are attracted. This game leans kind of heavily on the latter; in fact, if you ignore the girl and just complete your mission, you can only score 10% of the points!

This game is both easy and hard. It has many objectives, but you can end the game at any time. Winning at all is super easy; getting the maximum score is incredibly hard.

Smells and sounds matter in this game, as does physics. Objects can be pushed around, etc.

I do think it's a bit too hard to complete fully, and somehow I found the open-ended nature of the game a little less personally satisfying than his other games, including my favorite, Nightfall, which has stronger pacing. However, it's clear why this game was a candidate for (and winner of) the XYZZY Best Game award: it is impeccably polished, responsive, and clever.
