There are several reasons why it wasn't released for the PS2:
* PS2 release date: The PS2 launched in 2000, several years after the original release of Tomb Raider 2. By that point, the game was considered quite old.
* Focus on newer titles: Game developers typically focus on releasing new games for newer consoles. It would be a less profitable move to port an older game to a newer system.
* Technical limitations: Porting games to a new platform can be a challenging process, particularly for older games. The PS2 hardware may have required significant modifications to the game code to run properly.
You can play Tomb Raider 2 on a PS2 if you purchase the PS1 classic version of the game.
