2D Games are still quite popular eventhough there are 3D games everywhere on the internet. Nowadays, 2D games have come in the form of Flash games. You can search and play many 2D games online, but most site don't provide download of the online flash game (unless you use flash downloader to download the game).
Last night, when I was searching for free games, I found a site called 2Dplay. This site provides very nice games to play online. But we can also download the games. There are more than 50 kinds of games to download. Click
