I apparently have over $500 of unplayed games. However, looking at my library there's a lot that I've played through that it shows zero hours, whether I used a script loader because of mods or for some reason it just doesn't show that I've played the game (Bioshock series for some reason. I've played them all through).
I've also never payed full price for a game. Patient gamers unite! Just not right away.
Not an expert, but I've read it's easiest to use jupiter to bleed off enough velocity to fall into our sun.
