Back when I was a newbie to the internet and before I found out about Youtube and deviantArt, I went on several websites that had Flash Games. I actually had a nickelodeon account which I'm pretty sure is dead by now. I loved the Rugrats and SpongeBob flash games that they had.
Several other websites include Addictinggames.com: [link]
and the best, Mostfungames.com: [link]
These websites hold up a lot of nostalgic value for me, and I thought it'd be great if you could check them out.
A lot of fun games including Bloons, Halloween Escape, Electric Man 2, and several, SEVERAL more.
