Since the V12 version had already been established for this model, there were some disputes regarding these sub-versions.
Although Sony placed little emphasis on online gaming during its first year, all that changed because of the launch of the online-capable Xbox.
Developers also complained that it was difficult to develop for the system, with little in the way of reference material from Sony for its exotic architecture.
Many analysts predicted a close 3-way matchup between the PS2 and its soon-to-be-released competitors Microsoft Xbox and Nintendo GameCube, noting that the PS2's graphics were inferior but that it had the advantage of a head start, and had a wide assortment of games of every genre (Xbox's strength was in its hardware; GameCube was the cheapest of the 3 consoles).
The PS2 also supports PS1 memory cards (for PS1 game saves only) and controllers (the PS2's Dual Shock 2 controller is essentially a slightly upgraded PS1 Dual Shock).
The device was poorly received, with some major features absent from the first revisions of the hardware, and has thus far experienced very weak sales in Japan, in spite of major price drops [5].
The PS2 hardware can read both compact discs and DVDs.

As a result, although Sony and Nintendo both started out late and although both followed a decentralized model of online gaming where the responsibility is up to the developer to provide the servers, Sony's efforts made PS2 online gaming a big success.

Only a few million users had obtained consoles by the end of 2000 due to manufacturing delays.

The PlayStation 2 had a difficult start.
V3 has a substantially different internal structure from the subsequent revisions, featuring several interconnected printed circuit boards.
