i used to go on addictinggames, till NICKELODEAN bought it (in case you didnt know that) and turned it into a crapload. I still wish they would put stuff like gunny bunny on here
The old maker of ADDG make Onemorelevel, you should try it. Besides its low supply of games, its a good non-spam website.
I have always gone to a plethora of sites: OneMoreLevel, Kongregate, Not Doppler, Dan-Ball, Ninja Kiwi (more recent), and Newgrounds (more recent) cover most of it (including Armor Games of course).
Armor Games is very professional and doesn't overload you with flashy backgrounds and ads, so I would rank it in the top 3 for the game sites I visit. Kongregate is also good; however, it is very lenient with its rules. OneMoreLevel has a great assortment of games, but no user-to-user interaction.
The first ever game site I ever was on was Miniclip :P. I then got to Xgenstudios, played stick arena ballistic for a long time, then addicting games, played the world's hardest game for a long time, beat it too many times >.<, then found this awesome site lol.
Addicting games (but now it seems to lag a lot for me), Miniclip (which still has some good stuff like the Heli Attack games), and Ben Olding Games (which is still awesome but most of his games are now on Armor so that's why I go here).
My first one was agame.com. It's a pretty bad site, but for some reason I've only been there for like two years. AG was second for me, I think I found it following the link in Stormwinds' preloader. I've visited many gaming sites since then, but kongregate and newgrounds were the only ones comparable to AG.
Before this site I went to Andkon Arcade. They had a ton of games, but none were actually made by the site. I discovered AG through Andkon. They had tons of games they had added from the AG site, so one day I decided to click the link (I think it was in warfare 1917) and found this. A few days later, I joined the community.
I started off at miniclip and nitrome. I then went to addictinggames a few times and realized that all of there good games come from here, so I went here and stayed.
ArmorGames was the first gaming site that I created an account for. I think I visited CrazyMonkeyGames first because in study hall it was one of the few sites that wasn't blocked by the school. The only two gaming sites that I have an account for is ArmorGames and Kongregate.
addictinggames.com was my first one... well nick.com was first hehe but then addictinggames, then maxgames.com, then armorgames.com and now it is my favorite
