Roundabouts are the driving force behind a new game

About Roundabouts, from BoardGameGeek:

Roundabouts is a 2-4 player tile-laying card game. Players take turns drawing and placing square cards to create a grid of winding and charming roundabouts. While most cards are quarters of circles with a few arrows here and there, some cards have some extra text on them that increases (or decreases) their scoring power. The goal of the game is to score the most points out of everyone else when the game ends. Points are gained by finishing a roundabout. -description from the designer
