Do you remember playing Trek? And I mean OLD Trek games, from the 1970s or 1980s. A text grid was your map, and imagination was your graphics and gameplay. Well good news, everyone! Now you can relive those crazy days on your iPhone. If you have never played a game like this before, well, give it a go. You never know - you might like the warm thrill of confusion.
