Tetris: New Century

Tetris: New Century is a game exclusive to Tetris Collection for the PlayStation 2, and also includes some classic Sega Tetris games.
Although the game shares the same appearance as the arcade Tetris games by Sega, this game uses the current Guideline and features all gameplay modes and an "Extra" mode.
I normally play without the Ghost Piece, but I seem to do better with it...

I'm not a huge fan of the Tetris Guideline, personally. Some stuff is good (like ghost pieces) but particularly the randomization rules I find make the game too predictable.
