Well I'm not sure how "retro" this game is but it certainly brings me right back to my elementary/junior high days of watching game tutorials, not specifically club penguin but certainly runescape. The only thing that is missing is the old youtube layout with several "Halo 4 TRAILER NEW!!" videos with 1/5 stars.
While there isn't much in the way of gameplay its a funny little throwback to a time pre-dating youtube drama, multiple ads, and videos longer than about ten minutes.
Out of curiosity where did you get all the windows XP images, did you just take a screenshot of an old computer or find it online?
In conclusion, a nice little So Bad Its Good experience.
