:D
I play a game (offline) that's called "Jets'n'Guns" (extremely corny name, if you ask me... and the plot is cr@p... but I like it)
It's a 2D spaceship shooter (side view, not top view), but with some really wicked graphics and effects. Basically what you do is you just fly around in your spaceship/jet/whatever with some big guns, shooting everything and anything that moves, earning money to buy bigger guns to blow even more stuff up, to get even more money to... you get the picture.
I'm in it for the "blowing a lot of stuff up" part - I noticed it's very relaxing. If I get round to it, I'll make a couple of screenshots.
