And they do mean strange! You play as the captain of a space vessel who is sent on an assignment to explore, collect exotic lifeforms and treasures, and trade your way to riches.

Upgrade your ship and weapons along the way. Every time you play (games can last from 5 to 20 minutes), you encounter a different configuration of planets, allies, enemies, phenomena, and treasures; each new game's star map and scenario is randomly generated, giving the game a whole lot of replayability (although we're not sure it's truly infinite).

One hitch is that fighting battles with the variety of hostile aliens you'll encounter can be tedious—and while you can speed them up, you're basically just watching the combat unfold. Still, SAIS is an original with great colors and sounds.
