Which Do You Consider More Successful: PS1 or PS2?

[SvennoJ]

The question is how much did DVD playback play into the success of the PS2.

PS1 established the brand, yet PS2 benefited a lot from the new DVD format. Which Sony tried to replicate with the PS3 yet blu-ray never surpassed DVD, never came anywhere in the vicinity of DVD at its peak.

PS2 doubled as a DVD player while the competition was using cartridges and XBox required an add-on.

But in the end I'll say PS2 was more successful as it established a lot of great new franchises that established enough of a loyal fan base to save the ps3.
