I played this game and I love it... I love how it doesn't make old card obsolete (unless you're playing multiplayer,) and how it makes the duels shorter compared to the real game! I didn't follow Yu-Gi-Oh after 5Ds so this game is refreshing!

Each player starts with 4000 life points instead of 2000.

It's 8000 in the real game not 2000. The version that used 2000LP was the early anime version but it also used different cards than the ones we know right now.
