The PS2 has great features that come with it! The number 1 feature is the ability for it to play PlayStation 1 games. This has to be the best feature since it gives you access to 1000s of PSX games and you still have the hundreds of PS2 game already released! Another feature is the ability to play DVDs and CDs ( burned CDs too) . The PS2 doesnt come with 4 controller ports, but only 2. Although you can get a multi-tap, which will let you have 4 players.
There is also a Network Adapter available which will let you play games online. Some of the more popular online games are SOCOM US Navy SEALs ( broadband only) , Frequency, Twisted Metal: Black Online ( comes free with the Network Adapter) , and Madden 2003. These are just some of the many great features that PS2 has to offer. The features are great!
There is also a hard drive for PS2, but it is only released in Japan as I am writing this review. The hard drive is required to play some games online like Everquest Online and Final Fantasy XI.
Overall, there are lots of great features on the PS2.
