Mission style gameplay will allow you to take breaks in the story. Characters are interesting enough to be memorable. Action is dumb enough to be not.

Quick one-playthrough type of game. Play when you are in the mood of evolving a galaxy.

Unique artstyle, interesting gameplay. Try to play at least 3 times. After it gets too hard, move on.

Game worth spending time on. Can me passed in one sit-through. Pay attention to the story and the message.

Quick game (pretty easy to loose) but the UI is refreshing. Sink a few hours (until you figure out the best strategy) and move on.

This is a bit more addictive than the first one, and a little more of a chore, but the ending is worth it. Play it over the course of few days.

Treat portal as a story game and not so much a puzzle game. This will allow you to enjoy it. Great game for playing a level and stopping.

This might suck you in, but it is time well wasted. Note, you might only play this once (without multiple replays as the game suggests).

Good tetris replacement and relaxation game. You might only play a few hours of this, so get it on sale.
