Doctor Dirck
Traveler
Kadeem Alford a medium sized League of Legends streamer still plays this game. I watch his other stuff besides league because I think he's funny but it's so weird you mention that website and I just saw it for the first time the other day through him.-PuzzlePirates: Very interesting concept of an MMO that is sadly a ghost town.
cheatcodes.com
I used this site a long time ago and I remember super liking it. I even printed out some cheat codes from time to time. This website was cool because what they called 'cheats' weren't the literal definition of cheats but oftentimes cool bugs, strategies or cool things about the game you wouldn't otherwise know (maybe trivia?) An example is for Star Wars Knights of the Old Republic the underwear your character wears when their armor is removed is different depending on the Jedi robes you wore before they were removed. So dumb but you get like 50 of those little tidbits about a game and it just made it awesome.
cheatcc.com
I used cheatcc a lot and this was where you went if you wanted a reliable more complete list of cheat codes. Unfortunately xbox 360 and ps3's achievements and trophies kind of ruined the site for me because it was just lists and lists of achievements and how to get them.
ask.com
I never used this website but my Grandma did and even back in the day I thought it was corny and weird. It was funny years and years later to see her still use it and to still format her searches like a question. "Jeeves, what movies are showing tonight?" I suppose jokes on me though because now that the technology is here to give you a good answer that's basically what Alexa is.
The Old Barbie Website (no clue what the URL would have been then)
I never played this, but when my sister and I would have computer time we got it so sparingly it was still worth it to watch each other use it even if we had no interest in what the other was doing. I remember you could click on so much shit on this screen and there was like a minigame or animation or audio quip that played for EVERYTHING. Click on the cat? *Meow* Click on the gumball machine? *Gumball rolls out* Click on the CD player? Music would play.
webkinz.com
I bought my sister a Webkinz when we were kids for her birthday and she figured out the code let her get one of these animals online. This I actually kind of liked to play too I liked the daily games you can play sort of like Neopets.
Facebook.com/Mafia Wars
This was some mafia game on Facebook years ago you could play maybe some of you remember it. I played it even a couple years before this website design which seems to be pushing the iphone version. I remember this was the first game I experienced the "energy" model of gameplay. More than anything I think it was probably just annoying for my mom's friends to get invited to the game every time I needed energy for a raid; similar to Farmville I suppose.
