What a rushed, poorly thought-out end to an otherwise great game.

For spoiler: It's a stud fountain...but you had to buy everything to get 100% so it's actually useless.

I co-op'd the game with my little sister and we came up with two better ends:
1. You pull the lever on Yavin and a new planet shows up on the map. Maybe something like Lego City. We like this one only because we enjoyed that secret last time. It was so different to everything else.
2. A cutscene of the Yavin medal ceremony, showing all the characters you've met along the way and all the planets you've been to. And when the player reaches the stage and takes the medal it's revealed it's...Darth Jar Jar! Nice, silly, wholesome ending looking back on the last 40-hours and secret character unlocked.

I mean, that's what it was all the way back in the first Lego Starwars game. granted, that was more than a decade ago, so maybe that's not an excuse.
